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…
Integral equation with maxima via fibre contraction principle
Abstract The aim of this paper is to emphasize the role of the fibre contraction principle in the study of…
Stratified equatorial flows in cylindrical coordinates with surface tension
Abstract This paper considers a mathematical model of steady flows of an inviscid and incompressible fluid moving in the azimuthal…
On equilibrium in control problems with applications to evolution systems
Abstract In this paper we examine a mutual control problem for systems of two abstract evolution equations subject to a…
Spherical Shepard-Bernoulli operator
AbstractWe consider the problem of interpolating large sets of scattered data on the sphere using Shepard-Bernoulli operators constructed based on…
