Existence of renormalized solutions of degenerate elliptic-parabolic problems
Kaouther Ammar, Petra Wittbold · Proceedings of the Royal Society of Edinburgh Section A Mathematics · 2003
We consider a general class of degenerate elliptic-parabolic problems associated with the equation b(υ)t = div a(υ, Dυ) + f. Existence of renormalized solutions is established for general L1 data. Uniqueness of renormalized solutions has already been shown in a previous work.
