On the collapsing sandpile problem

WebPreviously, these problems were solved for the special case in which the inequality is simply variational. Here, we introduce a regularized mixed formulation involving both the primal (sand surface) and dual (sand flux) variables. We derive, analyse and compare two methods for the approximation, and numerical solution, of this mixed problem. WebRelevant bibliographies by topics / Collapsing sandpile.
