Convex Symmetrization for Anisotropic Elliptic Equations with a lower order term
arXiv:2008.03754
Abstract
We use "generalized" version of total variation, coarea formulas, isoperimetric inequalities to obtain sharp estimates for solutions (and for their gradients) to anisotropic elliptic equations with a lower order term, comparing them with the solutions to the convex symmetrized ones.
