On improved estimates for parabolic equations with double degeneracy
Mikhail Dmitriyevich Surnachev · Proceedings of the Steklov Institute of Mathematics · 2012
We obtain improved pointwise estimates for solutions to nonlinear parabolic equations with double degeneracy. These estimates differ from the classical estimates known for the linear case in that the supremum of the modulus of a solution is estimated by the sum of two powers of the integral norm of the solution.
