Nonlinear Analysis: Theory, Methods & Applications, 1997
It is well known that the radiative heat flux is a function of temperature. In certain radiative heat transfer it is of interest to devise methods for evaluating radiation function by using only measurements taken outside the medium. This paper seeks to determine some unknown radiation functions those depend only on the heat flux in a radiative heat ...

In this Chapter we study some pilot models of parabolic variational and hemivariational inequalities. The Chapter is primarily based on the works of Brezis [29], Goeleven and Motreanu [79], [91], Miettinen [125] and Quittner [156].

Some overdetermined parabolic problems
Mathematical Methods in the Applied Sciences, 1999The paper considers two classes of overdetermined initial boundary value problems of parabolic type. Let \(\Omega\) be a bounded domain \(\mathbb{R}^N\) with a \(C^{2+\varepsilon}\) boundary \(\partial\Omega\). The following initial boundary value parabolic problem defined in \(\Omega\times (0,T)\) as \[ g \bigl(u,|\nabla u|^2u,_i\bigr),_i+f\bigl(u ...

Symmetrization in parabolic neumann problems
Applicable Analysis, 1991We consider the Cauchy-Neumann problem for parabolic operators of the kind: on a smooth cylinder [0,T]×Ω. By symmetrization techniques we establish for the solution u of this problem an estimate of the kind: where U is the solution of a symmetrized problem and u(t)*(·) is the decreasing rearrangement of u(t,.).

Let Ω be a Lipschitz bounded open subset of ℝ n with boundary Г. Denote by Г D some measurable subset of Г (for the measure dσ(x)) and by Г N the complement of Г D in Г — that is to say $$ {\Gamma_N} = \Omega \backslash {\Gamma_D} $$ (12.1) .
