AbstractThis article presents numerical investigations on accuracy and convergence properties of several numerical approaches for simulating steady state flows in heterogeneous aquifers. Finite difference, finite element, discontinuous Galerkin, spectral, and…

Read More ## Common fixed points for Presic operators via simulation functions

AbstractIn this paper, using the concept of simulation function we present existence and uniqueness results for coincidence and common fixed points related to some Presic type operators in the framework …

Read More ## Some fixed point results regarding convex contractions of Presić type

AbstractIn the present paper, we introduce new types of Presić operators. These operators generalize the well-known Istrăţescu mappings, known as convex contractions. Also, we study the existence and uniqueness of…
