Existence for Nonlinear Evolution Equations and Application to Degenerate Parabolic Equation [PDF]

open access: yesJournal of Applied Mathematics, 2014
We consider an abstract Cauchy problem for a doubly nonlinear evolution equation of the form d/dt𝒜u+ℬu∋ft in V′, t∈0, T, where V is a real reflexive Banach space, 𝒜 and ℬ are maximal monotone operators (possibly multivalued) from V to its dual V′.

On a Nonlinear Degenerate Evolution Equation with Nonlinear Boundary Damping [PDF]

open access: yesJournal of Applied Mathematics, 2015
This paper deals essentially with a nonlinear degenerate evolution equation of the form Ku″-Δu+∑j=1nbj∂u′/∂xj+uσu=0 supplemented with nonlinear boundary conditions of Neumann type given by ∂u/∂ν+h·, u′=0.

A Class of Fractional Degenerate Evolution Equations with Delay [PDF]

open access: yesMathematics, 2020
We establish a class of degenerate fractional differential equations involving delay arguments in Banach spaces. The system endowed by a given background and the generalized Showalter–Sidorov conditions which are natural for degenerate type equations. We

Influence of a nonlinear degenerate diffusion on an advection-diffusion equation in a diffuse interface framework* [PDF]

open access: yesESAIM: Proceedings and Surveys, 2023
This work is motivated by the modelling a liquid-vapour flows with phase transition describing the evolution of the coolant within an heat exchanger (e.g. the core of a Pressurized Water Reactor).

L ∞ $L^{\infty }$ decay estimates of solutions of nonlinear parabolic equation

open access: yesBoundary Value Problems, 2021
In this paper, we are interested in L ∞ $L^{\infty }$ decay estimates of weak solutions for the doubly nonlinear parabolic equation and the degenerate evolution m-Laplacian equation not in the divergence form. By a modified Moser’s technique we obtain L ∞

Electron-acoustic solitons in dense electron–positron–ion plasma: Degenerate relativistic enthalpy function

open access: yesResults in Physics, 2022
An enthalpy function Hj∝1+ηj2is deduced from the density of states for degenerate relativistic charged particulate. Here ηj=pj/mjc2stands for the relativistic factor, pjmjis the Fermi momentum (mass) for the jth degenerate relativistic species and c ...

Quasilinear degenerate evolution equations in Banach spaces [PDF]

open access: yesJournal of Evolution Equations, 2004
The paper is concerned with the Cauchy problem for the quasilinear degenerate evolution equation of parabolic type in a Banach space \(X\): \[ {{dMv}\over{dt}} +L(Mv)v=F(Mv), \quad \;Mv(0)=u_0, \quad ...
