Boundary Value Problems for Some Quasilinear Parabolic Equations Under Minimal Conditions on the Coefficients

open access: yesMathematics
Quasilinear parabolic boundary value problems are considered. Sharp conditions on the data ensuring the existence and uniqueness of solutions in Sobolev classes Wp1,2(Q)(p>(n+2)/2 are exposed.

Locally Invariant Manifolds for Quasilinear Parabolic Equations

open access: yesRocky Mountain Journal of Mathematics, 1991
The paper is concerned with the geometric study of an evolution equation of the form \(x'-Lx=f(t,\lambda,x)\), where \(L:D(L)\to X\) is the generator of a holomorphic semigroup and the nonlinearity \(f\) acts essentially from some interpolation space \(D_ L(\theta+1)\) to \(D_ L(\theta)\).

Existence of solutions for quasilinear parabolic equations at resonance

open access: yesElectronic Journal of Differential Equations, 2013
In this article, we show the existence of nontrivial solutions for a class of quasilinear parabolic differential equations. To obtain the solution in a weighted Sobolev space, we use the Galerkin method, Brouwer's theorem, and a compact Sobolev-type ...
