Weba sandpile problem studied recently by Aronsson et al. [2], Evans et al. [15] and Prigozhin [20,21]. In these works, the (dynamic) problem is formulated as a parabolic equation that contains the p-Laplacian with large p: »x(0,oo), x {t = 0}, and also their limits whe —»n oo p•. The limit problem is in fact equivalent to the WebIn this paper, we introduce a new model for the collapsing sandpile and we prove existence and uniqueness of a solution for the corresponding initial value problem. Moreover, we prove the convergence of the time-stepping approximation of the solution. We use subgradient flows for variational problems with time dependent gradient constraints. determination of calcium hardness in water

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.
