Sharp decay rate and asymptotic simplification for a quasilinear heat equation

Maryam Al Hajjar, Ioana Ciotir, Matthias Täufer

We study the decay rate for a quasilinear heat equation of the form $\dot{u}-\Delta u=\mathrm{divB}(\nabla u)$. The term on the right-hand-side is interpreted as a nonlinear per…
