The frequency-dependent Wright-Fisher model: diffusive and non-diffusive approximations [PDF]

, 2013
. We study a class of processes that are akin to the Wright-Fisher model, with transition prob-abilities weighted in terms of the frequency-dependent fitness of the population types. By considering an approximate weak formulation of the discrete problem,

Carleman estimates and null controllability of a class of singular parabolic equations

Advances in Nonlinear Analysis, 2018
In this paper, we consider control systems governed by a class of semilinear parabolic equations, which are singular at the boundary and possess singular convection and reaction terms.

On some parabolic problems with measure sources

Moroccan Journal of Pure and Applied Analysis, 2019
One of the recent advances in the investigation of nonlinear parabolic equations with a measure as forcing term is a paper by F. Petitta in which it has been introduced the notion of renormalized solutions to the initial parabolic problem in divergence ...

System of degenerate parabolic p-Laplacian

Open Mathematics
In this article, we study the mathematical properties of the solution u=(u1,…,uk){\bf{u}}=({u}^{1},\ldots ,{u}^{k}) to the degenerate parabolic system ut=∇⋅(∣∇u∣p−2∇u),(p>2).{{\bf{u}}}_{t}=\nabla \hspace{0.25em}\cdot \hspace{0.25em}({| \nabla {\bf{u}}| }^
