Abstract: We construct novel flux approximation schemes for the semidiscretized incompressible Navier–Stokes equations by finite‐volume method on a staggered mesh. The calculation of the cell‐face fluxes has been done by solving appropriate local non‐linear boundary value… read more here.

Abstract: Our aim is to construct high order approximation schemes for general semigroups of linear operators $P_{t},t\geq 0$. In order to do it, we fix a time horizon $T $ and the discretization steps $h_{l}=\frac{T}{n^{l}},l\in \mathbb{N}$… read more here.

DOI: 10.1007/s10479-018-3111-9
Abstract: Stimulated by salient applications arising from power systems, this paper studies a class of non-linear Knapsack problems with non-separable quadratic constrains, formulated in either binary or integer form. These problems resemble the duals of the… read more here.
