TL;DR: In this article, the authors proved sharp bounds on the tails of the Levy exponent of an operator semistable law on R^d, and applied these bounds to explicitly compute the Hausdorff and packing dimensions of the range, graph, and other random sets describing the sample paths of the corresponding operator semi-similar Levy processes.
Abstract: This paper proves sharp bounds on the tails of the Levy exponent of an operator semistable law on $\mathbb R^d$. These bounds are then applied to explicitly compute the Hausdorff and packing dimensions of the range, graph, and other random sets describing the sample paths of the corresponding operator semi-selfsimilar Levy processes. The proofs are elementary, using only the properties of the Levy exponent, and certain index formulae.

TL;DR: In this paper, the authors derived bounds for the errors generated by truncating or replacing small jumps by a Brownian motion with the same variance, and showed that these two types of approximations are both error-prone.
Abstract: The pricing of options in exponential Levy models amounts to the computation of expectations of functionals of Levy processes. In many situations, Monte Carlo methods are used. However, the simulation of a Levy process with infinite Levy measure generally requires either truncating or replacing the small jumps by a Brownian motion with the same variance. We will derive bounds for the errors generated by these two types of approximation.

TL;DR: In this paper, the authors consider an interacting particle system in the space variable of a system of stochastic differential equations driven by Levy processes and prove that the empirical density process converges uniformly to the solution of the $d$-dimensional fractal conservation law.
Abstract: In this paper we consider an interacting particle system in $\mathbb{R}^d$ modelled as a system of $N$ stochastic differential equations driven by Levy processes. The limiting behaviour as the size $N$ grows to infinity is achieved as a law of large numbers for the empirical density process associated with the interacting particle system. We prove that the empirical process converges, uniformly in the space variable, to the solution of the $d$-dimensional fractal conservation law.

TL;DR: In this article, the Hunt variance gamma process (VGPM) is used to model the risk-neutral distribution of future stock prices, and a continuous-time Markov chain approximation is found to fit the S&P 500 futures option surface.
Abstract: In this dissertation we develop a spatially inhomogeneous Markov process as a model for financial asset prices. This model is called the Hunt variance gamma process. We define it via its infinitesimal generator and prove that this generator induces a unique measure on the space ofcádì ag functions. We next describe a procedure to do computations with this model by finding a continuous-time Markov chain approximation. This approximation is used to calibrate the model to fit the S&P 500 futures option surface. Next we investigate specific characteristics of the process, showing how it differs from both Lévy and Sato processes. We conclude by using the calibrated model to answer questions about properties of the risk-neutral distribution of future stock prices. We observe a more accurate fit to the risk-neutral term structure of volatility, skewness, and kurtosis, and the presence of mean-reversion in conditional probabilities involving large jumps. Dedication There is only one person to whom I can dedicate this thesis. And though she will probably never read more than a page of it, I couldn't have done it without her. Mary, thanks for everything. I love you. ii Acknowledgments There are so many people who have contributed either directly or indirectly to this dissertation. It is impossible for me to acknowledge everyone who has helped me in some manner during my time at the University of Maryland. Nevertheless, I would be negligent if I didn't at least make an effort to mention those who have contributed so much. To start, I have to mention my adviser, Dr. Dilip Madan. His enthusiasm and expertise piqued my interest in mathematical finance initially. As I learned more, I realized just how knowledgeable he was. But what impressed me most was his willingness to share that knowledge with his students in seminars and private conversations. Without his ideas, suggestions, and recommendations, I never would have reached this point. I would also like to acknowledge the members of my committee for their work in reviewing and improving my work. and Dr. Alt, thank you for taking time to help me. During the last few years, Dr. Balan has been especially kind in assisting me with a number of administrative details, for which I thank him. Along these lines, I am grateful to the entire Norbert Wiener Center for allowing me to attend conferences, classes, and seminars throughout my time in Maryland. It is fitting that …

TL;DR: In this article, the authors revisited the classical results on the generalized St Petersburg sums and analyzed how the limit depends on the value of the maximum, and obtained an infinite sum representation of the distribution function of the possible semistable limits.
Abstract: In this paper, we revisit the classical results on the generalized St. Petersburg sums. We determine the limit distribution of the St. Petersburg sum conditioning on its maximum, and we analyze how the limit depends on the value of the maximum. As an application, we obtain an infinite sum representation of the distribution function of the possible semistable limits. In the representation, each term corresponds to a given maximum, in particular this result explains that the semistable behavior is caused by the typical values of the maximum.

TL;DR: In this article, several definitions of the Riesz fractional Laplace operator in R^d have been studied, including singular integrals, semigroups of operators, Bochner's subordination, and harmonic extensions.
Abstract: This article reviews several definitions of the fractional Laplace operator (-Delta)^{alpha/2} (0 < alpha < 2) in R^d, also known as the Riesz fractional derivative operator, as an operator on Lebesgue spaces L^p, on the space C_0 of continuous functions vanishing at infinity and on the space C_{bu} of bounded uniformly continuous functions. Among these definitions are ones involving singular integrals, semigroups of operators, Bochner's subordination and harmonic extensions. We collect and extend known results in order to prove that all these definitions agree: on each of the function spaces considered, the corresponding operators have common domain and they coincide on that common domain.

Abstract: The purpose of this review article is to give an up to date account of the theory and applications of scale functions for spectrally negative Levy processes. Our review also includes the first extensive overview of how to work numerically with scale functions. Aside from being well acquainted with the general theory of probability, the reader is assumed to have some elementary knowledge of Levy processes, in particular a reasonable understanding of the Levy–Khintchine formula and its relationship to the Levy–Ito decomposition. We shall also touch on more general topics such as excursion theory and semi-martingale calculus. However, wherever possible, we shall try to focus on key ideas taking a selective stance on the technical details. For the reader who is less familiar with some of the mathematical theories and techniques which are used at various points in this review, we note that all the necessary technical background can be found in the following texts on Levy processes; (Bertoin, Levy Processes (1996); Sato, Levy Processes and Infinitely Divisible Distributions (1999); Kyprianou, Introductory Lectures on Fluctuations of Levy Processes and Their Applications (2006); Doney, Fluctuation Theory for Levy Processes (2007)), Applebaum Levy Processes and Stochastic Calculus (2009).

TL;DR: A closed formula for prices of perpetual American call options in terms of the overall supremum of the Lévy process, and a corresponding closed formulas for perpetual American put options involving the infimum of the after-mentioned process are obtained.
Abstract: Consider a model of a financial market with a stock driven by a Levy process and constant interest rate. A closed formula for prices of perpetual American call options in terms of the overall supremum of the Levy process, and a corresponding closed formula for perpetual American put options involving the infimum of the after-mentioned process are obtained. As a direct application of the previous results, a Black-Scholes type formula is given. Also as a consequence, simple explicit formulas for prices of call options are obtained for a Levy process with positive mixed-exponential and arbitrary negative jumps. In the case of put options, similar simple formulas are obtained under the condition of negative mixed-exponential and arbitrary positive jumps. Risk-neutral valuation is discussed and a simple jump-diffusion model is chosen to illustrate the results.

TL;DR: In this paper, the authors review work on extreme events, their causes and consequences, by a group of European and American researchers involved in a three-year project on these topics.
Abstract: We review work on extreme events, their causes and consequences, by a group of European and American researchers involved in a three-year project on these topics. The review covers theoretical aspects of time series analysis and of extreme value theory, as well as of the deterministic modeling of extreme events, via continuous and discrete dynamic models. The applications include climatic, seismic and socio-economic events, along with their prediction. Two important results refer to (i) the complementarity of spectral analysis of a time series in terms of the continuous and the discrete part of its power spectrum; and (ii) the need for coupled modeling of natural and socio-economic systems. Both these results have implications for the study and prediction of natural hazards and their human impacts.
