Bifurcation analysis for a logistic elliptic problem having nonlinear boundary conditions with sign-definite weight Abstract: 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. The difficulty is to evaluate the weight and position of the moving Dirac mass es that desribe the population.

We will talk about its properties such as convexity, continuity and discontinuity and mention its realization and finiteness properties.

Enrico Valdinoci Weierstrass Institute Title: An automorphism is an homeomorphism of the space commuting with the shift map.


With the nonlinearity of combined type, the objective of our study is to prove existence of a bifurcation component of positive solutions from trivial lines and discuss its asymptotic behavior and stability.

This is joint work with Henk Bruin and Dalia Terhesiu. Joint work with Emmanuel Breuillard. 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. ecuacionfs

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 fiferenciales drug? This is joint work with Ian Morris from the University of Surrey. These methods involve, in particular, a modification of the Turing machine model and an operator on subshifts that acts by distortion.


Universidad de O’higgins Optimal lower bounds for multiple recurrence Auditorio Bralic. To draw a comparison, topological emergence quantifies how far from uniquely ergodic the system is. This is the consequence of a result by M. Puc-Chile A geometric approach to the cohomological equation for cocycles of isometries Auditorio Bralic Abstract: The solution converges to a sum of Dirac mass es supported on a hypersurface that results from the nonlinearity. The method developed for this purpose originates in 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. In a work with Mathieu Sablik, we made a step towards the limit, proving that the result of Hochman and Meyerovitch is robust under the linear version of this property where the minimal distance function is O n where n is the size of the two square blocks.

The analysis is carried out using bifurcation techniques, based on the Lyapunov and Schmidt method. We would like to give an introductory presentation of some equations which exhibit some nonlocal phenomena.

Moreover, regularity properties of the pressure map have been established in recent works by G. This is particularly interesting when the system has slow mixing properties, or, even more extreme, in the null recurrent case where the relevant invariant measure is infinite.

Septiembre – Seminario de Ecuaciones Diferenciales

Some additional theoretical questions as uniqueness for the limiting H. Determinantal point processes arise in a wide range of problems. These models are often simple to describe: Topological entropy is a way of quantifying the complexity of a dynamical system. However, models studied in statistical physics obey to strong dynamical constraints and there is still hope to include them into a sub-class of subshifts of finite type for which the entropy is uniformly computable this means that there is an algorithm which can provide arbitrarily precise approximations of the entropy, provided the precision and the local rules of the diferecniales.

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.


As an application, we extend the theory of factors of generalized Gibbs measures on subshifts on finite alphabets to that on certain subshifts over countable alphabets. I’ll also present examples of dynamical systems where this bound is essentially attained. Bifurcation analysis for a logistic elliptic problem having nonlinear boundary conditions with sign-definite weight. This means imposing that two patterns can be glued in any two positions in a configuration of the subshift, provided that the distance is great enough, where the minimal distance is a linear function of the size of these patterns.


We will show that a new type of Hamilton-Jacobi equation, with constraints, naturally describes this asymptotic. Escuela admin T This is a joint work with A.

The talk will first address this question for specific examples such as the sine-process, where one can explicitly write the analogue of the Gibbs condition in our situation.

We will motivate this problem, and discuss what is new: For non-compact situations, the existence of equilibrium measures has been successfully studied over the last years.

In these circumstances, is it possible to describe the dynamical evolution of the current trait? Often, the nonlocal effect is modeled by a diffusive operator which is in some sense elliptic and fractional. Buscar en este sitio. A strategy to understand the limit between the general regime where Hochman and Meyerovitch’s result holds and this restricted block gluing class is to quantify this property. Nonlocal equations in phase transitions, minimal surfaces, crystallography and life sciences.

We will explain how topological emergence is bounded from above in terms of the dimension of the ambient space.

Darwin, of population growth, selection and mutations. On the other hand, the new-born individuals can undergo small variations of the trait under the effect of genetic mutations. En esta charla nos interesamos en estudiar conos que pueden ser descritos por un lenguaje regular i.
