This is joint work with R. In a second part, we will turn to large deviations and talk about the recent result on the existence of large deviation principle for random matrix products.
Bifurcation analysis for a logistic elliptic problem having nonlinear boundary conditions with sign-definite weight Abstract: I’ll also present examples of dynamical systems where this bound is essentially attained. An automorphism is an homeomorphism of the space commuting with the shift map. The goal of this series of lectures is to formalize them and to discuss the exemple of resistance to therapy in cancer treatment; can an injection protocole diminish adaptation of cancer cells to the drug?
Although they provided a construction to realize some class numbers as the entropy of block gluing SFT, they did not prove a characterization, and this problem seems difficult.
Pursuing this idea, we are led to fundamentally new ways of quantifying dynamical complexity. Ubiobio Hidden Gibbs measures on shift spaces over countable alphabet Sala 2 Abstract: Universidad de O’higgins Optimal lower bounds for multiple recurrence Auditorio Bralic. We study the thermodynamic formalism for particular types of sub-additive sequences on a class of subshifts over countable alphabets.
Although it is known that it is possible to compute the entropy of one-dimensional version of these models by computing the greatest eigenvalue of a matrix which derives from the description of the subshift, this is not possible for multidimensional subshifts.
Septiembre – Seminario de Ecuaciones Diferenciales
As an application, we extend the theory of factors of generalized Gibbs measures on subshifts on finite alphabets to that on certain subshifts diferencisles countable alphabets. It consists of the implementation of Turing machines in hierarchical structures that emerge from the local rules. We will present in this talk a survey of various restrictions on these groups for zero entropy minimal subshifts.
However, it could be possible to find broader usacj for which the entropy is still computable. This is a joint work with A. Finally, we will make connections with random products of matrices.
A strategy to understand the limit between the general regime where Hochman and Meyerovitch’s result holds and this restricted block ecuacionss class is to quantify this property.
Often, the nonlocal effect is modeled by a diffusive operator which is in some sense elliptic and fractional. KAM theory reveals that non-ergodicity is somewhat typical among conservative dynamical systems, and metric emergence provides a way of measuring the complexity of the KAM picture.
This property means that two square blocks can be viewed in any relative positions in some element of the subshift provided that the distance between the two blocks is sufficiently large, with minimal distance not depending on the size of the blocks is a computable real number.
Puc-Chile A geometric approach to the cohomological equation for cocycles of isometries Auditorio Bralic Abstract: We will motivate this problem, and discuss what is new: We will then consider the general case, where, in joint work with Yanqi Qiu and Alexander Shamov, proof is given of the Lyons-Peres conjecture on completeness of random kernels. This is joint work with Ian Morris from the University of Surrey.
Seminario de Ecuaciones Diferenciales. A subshift is a closed shift invariant set of sequences over a finite alphabet. Difetenciales the work of R. The aim of this talk would be, after a presentation of the problem, to give an insight on the obstacles to this property in the initial construction of Hochman and Meyerovitch, using a construction slightly simpler to present, and on the methods used to overcome the obstacles.
Topological entropy is a way of quantifying the complexity of a dlferenciales system.
We show the variational principle for topological pressure. Bifurcation analysis for a logistic elliptic problem having nonlinear boundary conditions with sign-definite weight. For non-compact situations, the existence of equilibrium measures difefenciales been successfully studied over the last years.
Enrico Valdinoci Weierstrass Institute Title: We present boundary half-Harnack estimates and ecuaiones they can be used in studying the solvability and a priori bounds for fully nonlinear boundary value problems with quadratic growth in the gradient.
Formulario de Contacto facebook. Harnack estimates and uniform bounds for elliptic PDE with natural growth Abstract: These methods involve, uasch particular, a modification of the Turing machine model and an operator on subshifts that acts by distortion.
Mathematically, the interest comes from concentration effects after an appropriate rescaling. To draw a comparison, topological emergence quantifies how far from uniquely ergodic the system is.
On the other hand, the new-born individuals can undergo small variations of the trait under the effect of genetic mutations. However, these models and their physical constants, such as the entropy are difficult to apprehend with general methods, and involve specific properties of the considered model.
We present some geometrical tools in order to obtain solutions to cohomological equations that arise in the reducibility problem of cocycles by isometries of negatively curved metric spaces.
I will talk about ongoing work with Pierre Berger. I’ll present examples and questions.
