Szász–Mirakjan–Durrmeyer operators defined by multiple Appell polynomials
Abstract The paper aims at approximating functions through a sequence of linear positive operators of continuous type. First we define…
A fixed-point approach to control problems for Kolmogorov type second-order equations and systems
Abstract In this paper, the second-order differential equations and systems of Kolmogorov type are defined. With reference to population dynamics…
Iterative schemes for coupled flow and transport in porous media -Convergence and truncation errors
Abstract Nonlinearities of coupled flow and transport problems for partially saturated porous media are solved with explicit iterative L-schemes. Their…
