چکیده

In this paper we consider the homogenization of evolution problem associated with a jump process that involves three different smooth kernels govern jumps to/from parts domain. We assume spacial domain is divided into sequence two subdomains $$A_n \cup B_n$$ and have kernels, one controls from $$A_n$$ to , second $$B_n$$ third governs interactions between . Assuming $$\chi _{A_n} (x) \rightarrow X(x)$$ weakly in $$L^\infty $$ (and then _{B_n} 1-X(x)$$ ) as $$n \infty initial condition given by density $$u_0$$ $$L^2$$ show there an homogenized limit system which function X appear. When delta at point, $$\delta _{{\bar{x}}}$$ (this corresponds starts $${\bar{x}}$$ convergence along subsequences such $${\bar{x}} \in A_{n_j}$$ or B_{n_j}$$ for every $$n_j$$ large enough. also provide probabilistic interpretation equation terms stochastic describes movement particle $$\Omega according underlying converges distribution equation. focus our analysis Neumann type boundary conditions briefly describe end how deal Dirichlet conditions.

Nonlocal Impulsive Cauchy Problems for Evolution Equations

Of concern is the existence of solutions to nonlocal impulsive Cauchy problems for evolution equations. Combining the techniques of operator semigroups, approximate solutions, noncompact measures and the fixed point theory, new existence theorems are obtained, which generalize and improve some previous results since neither the Lipschitz continuity nor compactness assumption on the impulsive fu...

Homogenization for a Nonlocal Coupling Model

In [7, 8, 12] homogenization techniques are applied to derive an anisotropic variant of the bio-heat transfer equation as asymptotic result of boundary value problems providing a microscopic description for microvascular tissue. In view of a future application on treatment planning in hyperthermia, we investigate here the homogenization limit for a coupling model, which takes additionally into ...

Boundary-value Problems at Resonance with Three Dimensional Kernels

In this article, we consider the boundary-value problem x′′′(t) = f(t, x(t), x′(t), x′′(t)), t ∈ (0, 1), x′′(0) = m X i=1 αix (ξi), x ′(0) = l X k=1 γkx (σk), x(1) = n X j=1 βjx(ηj), where f : [0, 1] × R3 → R is a Carathéodory function, and the kernel to the linear operator has dimension three. Under some resonance conditions, by using the coincidence degree theorem, we show the existence of so...

Nonlocal in Time Problems for Evolution Equations of Second Order

In this paper, nonlocal in time problem for abstract evolution equation of second order is studied and theorem on existence and uniqueness of its solution is proved. Some applications of this theorem for hyperbolic partial differential equations and systems are considered and it is proved, that well-posedness of the mentioned problems depends on algebraic properties of ratios between the dimens...

Patch dynamics with buffers for homogenization problems

An important class of problems exhibits smooth behaviour on macroscopic space and time scales, while only a microscopic evolution law is known. For such time-dependent multi-scale problems, an “equation-free” framework has been proposed, of which patch dynamics is an essential component. Patch dynamics is designed to perform numerical simulations of an unavailable macroscopic equation on macros...
