Non-negative solutions of linear parabolic equations : an addendum
Null-controllability of one-dimensional parabolic equations
We prove the interior null-controllability of one-dimensional parabolic equations with time independent measurable coefficients.
Numerical simulation of a point-source initiated flame ball with heat losses
This article is devoted to the numerical study of a flame ball model, derived by Joulin, which obeys to a singular integro-differential equation. The numerical scheme that we analyze here, is based upon a one step method, and we are interested in its long-time behaviour. We recover the same dynamics as in the continuous case: quenching, or stabilization of the flame, depending on heat losses, and an energy input parameter.
