, 1995 . This paper introduces a discrete scheme for mean curvature motion using a morphological image processing approach. After briefly presenting an axiomatic approach of image processing and the mean curvature PDE, the properties of the proposed scheme are ...

Dipoles and Similarity Solutions of the Thin Film Equation in the Half-Line
, 1999 We consider non-negative solutions on the half-line of the thin film equation h t +(h n hxxx)x = 0, which arises in lubrication models for thin viscous films, spreading droplets and Hele-Shaw cells.

, 2016 Of concern are some classes of initial-boundary value differential problems associated with one-dimensional Fleming-Viot differential operators. Among other things, these operators occur in some models from population genetics to study the fluctuation of

A degenerate migration-consumption model in domains of arbitrary dimension
Advanced Nonlinear StudiesIn a smoothly bounded convex domain Ω⊂Rn ${\Omega}\subset {\mathbb{R}}^{n}$ with n ≥ 1, a no-flux initial-boundary value problem forut=Δuϕ(v),vt=Δv−uv, $$\begin{cases}_{t}={\Delta}\left(u\phi \left(v\right)\right),\quad \hfill \\ {v}_{t}={\Delta}v-uv ...

The Keller-Segel model with logistic sensitivity function and small diffusivity
, 2006 . The Keller-Segel model is the classical model for chemotaxis of cell populations. It consists of a drift-diffusion equation for the cell density coupled to an equation for the chemoattractant.

Gevrey Regularity and Local Well-Posedness for the HirotaSatsuma System
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria MatematicaIn this paper, we examine the local well-posedness of the initial value problem for the HirotaSatsuma system within Gevrey spaces. This system, which consists of a coupled nonlinear dispersive partial differential equation, models the interactions ...
