Elliptic approximation of forward-backward parabolic equations
Fabio Paronetto · Communications on Pure & Applied Analysis · 2019
In this note we give existence and uniqueness result for some elliptic problems depending on a small parameter and show that their solutions converge, when this parameter goes to zero, to the solution of a mixed type equation, elliptic-parabolic, parabolic both forward and backward. The aim is to give an approximation result via elliptic equations of a changing type equation.
