Agnès Helmstetter,Agnès Helmstetter,Didier Sornette,Didier Sornette,Jean-Robert Grasso,Jean-Robert Grasso,Jørgen Vitting Andersen,Jørgen Vitting Andersen,Simon Gluzman,V. F. Pisarenko +9 more
TL;DR: In this article, the authors provide a physical basis for this phenomenological law based on a slider block model using a state and velocity-dependent friction law established in the laboratory, and use the slider block friction model to analyze quantitatively the displacement and velocity data preceding two landslides, Vaiont and La Clapiere.

Didier Sornette,Didier Sornette,Agnès Helmstetter,Jørgen Vitting Andersen,Jørgen Vitting Andersen,Simon Gluzman,Jean-Robert Grasso,Jean-Robert Grasso,V. Pisarenko +8 more
TL;DR: In this article, a simple physical model was proposed to explain the accelerating displacements preceding some catastrophic landslides, based on a slider-block model with a state and velocity-dependent friction law.
Journal ArticleDOI
Log-periodic route to fractal functions
TL;DR: It is suggested that growth processes, rupture, earthquake, and financial crashes seem to be characterized by oscillatory or bounded regular microscopic functions that lead to a slow power-law decay of A(n), giving strong log-periodic amplitudes.
Journal ArticleDOI
Self-similar factor approximants.
TL;DR: It is proved that the self-similar factor approximants are able to reproduce exactly a wide class of functions, which include a variety of nonalgebraic functions, and provide very accurate approximations, whose accuracy surpasses significantly that of the most accurate Padé approximant.

Self-similar exponential approximants
V. I. Yukalov,Simon Gluzman +1 more
Abstract: An approach is suggested for defining effective sums of divergent series in the form of self-similar exponential approximants. The procedure of constructing these approximants from divergent series with arbitrary noninteger powers is developed. The basis of this construction is the self-similar approximation theory. Control functions governing the convergence of exponentially renormalized series are defined from stability and fixed-point conditions and from additional asymptotic conditions when the latter are available. The stability of the calculational procedure is checked by analyzing cascade multipliers. A number of physical examples for different statistical systems illustrate the generality and high accuracy of the approach.
