Elliptic differential operators describe a wide range of processes in mechanics relevant to geo-energy applications. Extensively used reservoir modeling, the Finite Volume Method with TPFA can be consistently applied discretize only specific type application under severe assumptions. In this paper, we introduce positivity preserving Nonlinear Two Point Stress Approximation (NTPSA) based on rece...

Abstract In this paper, we study the optimal multiple stopping problem under filtration-consistent nonlinear expectations. The reward is given by a set of random variables satisfying some appropriate assumptions, rather than process that right-continuous with left limits. We first construct time for single problem, which no longer hitting processes. then prove induction value function can be in...

In this paper, the problem under consideration is multiobjective non-linear fractional programming problem involving semilocally convex and related functions. We have discussed the interrelation between the solution sets involving properly efficient solutions of multiobjective fractional programming and corresponding scalar fractional programming problem. Necessary and sufficient optimality...
