In this work, we adapt the epidemiological SIR model to study the evolution of the dissemination of COVID-19 in Germany and Brazil (nationally, in the State of Paraíba, and in the City of Campina Grande). We prove the well posedness and the continuo

In this paper, we consider the following nonlocal autonomous evolution equation in a bounded domain Ω in RN: ∂tu(x,t)=−h(x)u(x,t)+g(∫ΩJ(x,y)u(y,t)dy)+f(x,u(x,t)), where h∈W1,∞(Ω), g:R→R and f:RN×R→...

We show the normal hyperbolicity property for the equilibria of the evolution equation ∂m(r,t)/∂t=-m(r,t)+g(βJ*m(r,t)+βh), h,β≥0, and using the normal hyperbolicity property we prove the continuity (upper semicontinuity and lower semicontinu

In this work we consider the non local evolution problem \[ \begin{cases} \partial_t u(x,t)=-u(x,t)+g(\beta K(f\circ u)(x,t)+\beta h), ~x \in\Omega, ~t\in[0,\infty[;\\ u(x,t)=0, ~x\in\mathbb{R}^N\setminus\Omega, ~t\in[0,\infty[;\\ u(x,0)=u_0(x),~x\in

In this work we consider the nonlocal evolution equation with time-dependent terms which arises in models of phase separation in \(\mathbb {R}^N\) $$\begin{aligned} \partial _t u=- u + g \left( \beta (J*u) +\beta h(t)\right) \end{aligned}$$ under som

In this paper we consider the non local evolution equation $$ \frac{\partial u(x,t)}{\partial t} + u(x,t)= \int_{\mathbb{R}^{N}}J(x-y)f(u(y,t))\rho(y)dy+ h(x). %\,\,\, h \geq 0. $$ We show that this equation defines a continuous flow in both the spac
