Extinction of solutions of semilinear higher order parabolic equations with degenerate absorption potential

Yves Belaud, Andrey Shishkov

We study the first vanishing time for solutions of the Cauchy-Dirichlet problem to the semilinear $2 m$ -order ( $m \geq 1$ ) parabolic equation $u_{t} + Lu + a (x) ∣ u ∣^{q - 1} u = 0$ , $0 < q < 1$ wit…

On convergence in smooth gradient systems with branching of equilibria

V. A. Galaktionov, S. I. Pohozaev, A. E. Shishkov

T.I. Zelenyak's ideas and method of 1968 are shown to apply to N-dimensional second- and higher-order parabolic equtions and ensure a fast exponential convergence to degenerate equ…
