AbstractRandom walk methods are suitable to build up convergent solutions for reaction-diffusion problems and were successfully applied to simulations of transport…

Abstract This paper aims to highlight a class of integral linear and positive operators of Landau type which have affine functions as fixed points. We focus to reveal approximation properties…

AbstractIn this paper, we define and study a general class of convolution operators based on Landau operators. A property of these new operators is that they reproduce the affine functions,…

AbstractIn this paper we consider a general class of linear positive processes of integral type. These operators act on functions defined on unbounded interval. Among the particular cases included are…
