Abstract quasilinear parabolic equations

open access: yesMathematische Annalen, 1984
The author deals with an abstract quasilinear parabolic problem \(u'(t)=A(t,u(t))u(t)+f(t,u(t)), t>0\), \(u(0)=u_ 0\) in a Banach space X. His theorems on existence and uniqueness are such that a concrete quasilinear parabolic problem can be attacked without imposing growth conditions on the coefficients.

Feedback control for an abstract parabolic equation [PDF]

open access: yes, 1987
Abstract : In their previous paper, the authors considered the problem of the exponential stabilization of the heat equation with Neumann boundary conditions in the smooth and bounded domain OMEGA in R(exp n), where partial derivative/partial derivative nu denotes the differentiation in the direction normal to the boundary partial derivative OMEGA. The

First-Order Regular and Degenerate Identification Differential Problems

open access: yesAbstract and Applied Analysis, 2015
We are concerned with both regular and degenerate first-order identification problems related to systems of differential equations of weakly parabolic type in Banach spaces. Several applications to partial differential equations and systems will be given
