TL;DR: In this paper, the modified block iterative method is used to solve the convex feasibility problems for an infinite family of quasi-asymptotically nonexpansive mappings.
Abstract: The purpose of this paper is to use the modified block iterative method to propose an algorithm for solving the convex feasibility problems for an infinite family of quasi- -asymptotically nonexpansive mappings. Under suitable conditions some strong convergence theorems are established in uniformly smooth and strictly convex Banach spaces with Kadec-Klee property. The results presented in the paper improve and extend some recent results.

TL;DR: In this article, a hybrid projection method for finding a common element in the fixed point set of an asymptotically quasi-ϕ-none-expansive mapping and in the solution set of the equilibrium problem is considered.
Abstract: We consider a hybrid projection method for finding a common element in the fixed point set of an asymptotically quasi-ϕ-nonexpansive mapping and in the solution set of an equilibrium problem. Strong convergence theorems of common elements are established in a uniformly smooth and strictly convex Banach space which has the Kadec-Klee property.

TL;DR: An extragradient-type algorithm for solving bilevel pseudomonone variational inequalities using simple projection sequences is presented and the convergence of the iteration sequences generated by the algorithm is obtained.
Abstract: We present an extragradient-type algorithm for solving bilevel pseudomonone variational inequalities. The proposed algorithm uses simple projection sequences. Under mild conditions, the convergence of the iteration sequences generated by the algorithm is obtained.

TL;DR: In this article, the authors developed a general equilibrium framework to determine the spatial distribution of economic activity on (nearly) any surface with nearly any geography, combining the gravity structure of trade with labor mobility.
Abstract: We develop a versatile general equilibrium framework to determine the spatial distribution of economic activity on (nearly) any surface with (nearly) any geography. Combining the gravity structure of trade with labor mobility, we provide conditions for the existence and uniqueness of a spatial economic equilibrium and derive a simple set of dierential equations which govern the relationship between economic activity and the geography of the surface. We then use the framework to identify the underlying topography of productivities and amenities both in the United States and across the world. We nd that geographic location is an important determinant of the observed spatial distribution of income. Finally, we show how changing the underlying geography would aect the equilibrium distribution of economic activity.

TL;DR: This letter will study the problem of too little attention paid to the convergence issue of the fixed-point MCC algorithms and give a sufficient condition to guarantee the convergence of a fixed- point MCC algorithm.
Abstract: The maximum correntropy criterion (MCC) has received increasing attention in signal processing and machine learning due to its robustness against outliers (or impulsive noises). Some gradient based adaptive filtering algorithms under MCC have been developed and available for practical use. The fixed-point algorithms under MCC are, however, seldom studied. In particular, too little attention has been paid to the convergence issue of the fixed-point MCC algorithms. In this letter, we will study this problem and give a sufficient condition to guarantee the convergence of a fixed-point MCC algorithm.
