The correlation integral of a time series is a normalized coefficient that represents the number of close pairs of points of the series lying in phase space. It has been widely studied in a number of disciplines such as ...

We study a linear Langevin dynamics driven by an additive non-Markovian symmetrical dichotomic noise. It is shown that when the statistics of the time intervals between noise transitions is characterized by two well ...

We consider the following stationary Keller-Segel system from chemotaxis

In this paper we study the subcritical contact process on Zd for large times, starting with all sites infected. The configuration is described in terms of the macroscopic locations of infected regions in space and the ...

We study the positive stationary solutions of a standard finite-difference discretization of the semilinear heat equation with nonlinear Neumann boundary conditions. We prove that, if the absorption is small enough, compared ...

We obtain the critical points of a functional defined on L^2 (Ω×R^n ), which coincide with solutions for Boltzmann’s stationary equation.

A stationary inflection point (SIP) of the Bloch dispersion relation of a periodic system is a prominent example of an exceptional point degeneracy (EPD) where three Bloch eigenmodes coalesce. The scattering problem for a ...
