Parabolic reaction-diffusion systems with nonlocal coupled diffusivity terms [PDF]

, 2017
In this work we study a system of parabolic reaction-diffusion equations which are coupled not only through the reaction terms but also by way of nonlocal diffusivity functions.

Maximal regular boundary value problems in Banach-valued function spaces and applications

International Journal of Mathematics and Mathematical Sciences, 2006
The nonlocal boundary value problems for differential operator equations of second order with dependent coefficients are studied. The principal parts of the differential operators generated by these problems are non-selfadjoint.

On Positive Solutions of Some System of Reaction-Diffusion Equations with Nonlocal Initial Conditions [PDF]

, 2010
The paper focuses on positive solutions to a coupled system of parabolic equations with nonlocal initial conditions. Such equations arise as steady-state equations in an age-structured predator-prey model with diffusion.

Initial conditions and degrees of freedom of non-local gravity

Journal of High Energy Physics, 2018
We prove the equivalence between non-local gravity with an arbitrary form factor and a non-local gravitational system with an extra rank-2 symmetric tensor.

Feedback exponential stabilization of the semilinear heat equation with nonlocal initial conditions

Nonlinear Analysis, 2021
The present paper is devoted to the problem of stabilization of the one-dimensional semilinear heat equation with nonlocal initial conditions. The control is with boundary actuation.

Wave turbulence description of interacting particles: Klein-Gordon model with a Mexican-hat potential [PDF]

, 2015
In field theory, particles are waves or excitations that propagate on the fundamental state. In experiments or cosmological models one typically wants to compute the out-of-equilibrium evolution of a given initial distribution of such waves.
