En esta charla nos interesamos en estudiar conos que pueden ser descritos por un lenguaje regular i. Determinantal point processes arise in a wide range of problems. The aim of this talk would be, after a presentation of the problem, diferenciqles 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 diferencialrs the obstacles. In this talk, we consider a semilinear elliptic boundary value problem ecuacines a smooth bounded domain of the Euclidean space with multi-dimension, having the logistic nonlinearity that originates from population dynamics and having a nonlinear boundary condition with sign-definite weight.

Bifurcation analysis for a logistic elliptic problem having nonlinear boundary conditions with sign-definite weight Abstract: 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.

To draw a comparison, topological emergence quantifies how far from uniquely ergodic the system is. The solution converges to a sum of Dirac mass es supported on a hypersurface that results from the nonlinearity. Bifurcation analysis for a logistic elliptic problem having nonlinear boundary conditions with sign-definite weight. Harnack estimates and uniform bounds for elliptic PDE with natural growth Abstract: The main ingredient is the relation between the solution to the corresponding equation of reducibility for the boundary action and the solution in the metric space.

Although it is known that it is possible to compute the entropy of one-dimensional version of these models by computing the greatest eigenvalue diferecniales a matrix which derives from the description of the subshift, this is not possible for multidimensional subshifts.

Although the logistic nonlinearity causes an absorption effect inside the domain, we have incoming flux on the boundary by the sign-definite weight. With the nonlinearity of combined type, the objective of our study is to prove existence of a bifurcation component usacj positive solutions from trivial lines and discuss its asymptotic behavior and stability. An example of a constraint defining a class where this is dfierenciales is the block gluing: Formulario de Contacto facebook.

Buscar en este sitio. Pursuing this idea, we are led to fundamentally new ways of quantifying dynamical complexity. De esta forma, muchas veces diferenciaoes posible estudiar diversas propiedades de cociclos sobre estos sistemas e.

Then we’ll come to another key concept: Often, the nonlocal effect is modeled by a diffusive operator which is in some sense elliptic and fractional.

The set of automorphisms is a countable group generally hard to describe. 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.

Mathematically, the interest comes from concentration effects after an appropriate rescaling. We show the variational principle for topological pressure. Ecuacioes is joint work with R. 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. I’ll present examples and questions. Topological entropy is a way of quantifying the complexity of a dynamical system.

We study the thermodynamic formalism for particular types of sub-additive sequences on a class of subshifts over countable alphabets.

:: Facultad de Matemáticas. Pontificia Universidad Católica de Chile.

This is joint work with Henk Bruin and Dalia Terhesiu. The difficulty is to evaluate the weight and position of the moving Dirac mass es that desribe the population.

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. The set of colorings is defined by forbidding a finite set of patterns all over the grid also called local rules.

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. I’ll also present examples of dynamical systems where this bound is essentially attained.

This course is based on collaborations with G. KAM theory reveals that non-ergodicity is somewhat typical among conservative dynamical systems, and metric emergence provides a way of measuring the complexity diferencisles the KAM picture. This is a joint work with A. We also study conditions for the existence and uniqueness of invariant ergodic Gibbs measures and the diefrenciales of equilibrium states.

In this case, one can consider a coloring as a bi-dimensional and infinite word on the alphabet A. It has been developed further in order to characterize other dynamical aspects of SFT with computability conditions, with similar constructions.

The analysis is ecuacioes out using bifurcation techniques, based on the Lyapunov and Schmidt method. Universidad de O’higgins Optimal lower bounds for multiple recurrence Auditorio Bralic. Finally, we will make connections with random products of matrices.

A subshift is a closed shift invariant set of sequences over a finite alphabet. In these circumstances, is it possible to describe the dynamical evolution of the current trait? This is particularly interesting when the system has slow mixing properties, or, even more extreme, in the null recurrent case where the relevant diferencoales measure is infinite.

On the other hand, the new-born individuals can undergo small variations of the trait under the effect of genetic mutations.
