Study on Integrodifferential Evolution Systems with Nonlocal Initial Conditions

28 Jan at 8:52 am

AbstractThe work is concerned with systems of abstract integrodifferential equations with general nonlocal initial conditions. To allow the nonlinear terms…

Space-time upscaling of reactive transport in porous media

17 Jan at 11:11 am

AbstractReactive transport in saturated/unsaturated porous media is numerically upscaled to the spacetime scale of a hypothetical measurement through coarse grained…

On high-order conforming finite element methods for ill-posed Helmholtz problems

7 Jan at 7:23 am

Abstract We consider the numerical approximation of the linear ill-posed problem of unique continuation for the Helmholtz equation. We first…

On the Durrmeyer-type variant and generalizations of Lototsky–Bernstein operators

9 Nov 2021

Abstract The starting points of the paper are the classic Lototsky–Bernstein operators. We present an integral Durrmeyer-type extension and investigate…

Tikhonov regularization of a perturbed heavy ball system with vanishing damping

8 Nov 2021

AbstractThis paper deals with aa perturbed heavy ball system with vanishing damping that contains a Tikhonov regularization term, in connection…

On the Controllability of a System Modeling Cell Dynamics Related to Leukemia

8 Nov 2021

AbstractIn this paper, two control problems for a symmetric model of cell dynamics related to leukemia are considered. The first…

On a Volterra Integral Equation with Delay, via w-Distances

20 Oct 2021

AbstractThe paper deals with a Volterra integral equation with delay. In order to apply the w-weak generalized contraction theorem for…

Global random walk solvers for reactive transport and biodegradation processes in heterogeneous porous media

26 Aug 2021

AbstractFlow and multicomponent reactive transport in saturated/unsaturated porous media are modeled by ensembles of computational particles moving on regular lattices…

Functional differential equations with maxima, via step by step contraction principle

26 Aug 2021

AbstractT. A. Burton presented in some examples of integral equations a notion of progressive contractions on C([a, ∞[). In 2019,…

How many steps still left to x*?

14 Jul 2021

Abstract The high speed of $x_{k}\rightarrow x^\ast\in{\mathbb R}$ is usually measured using the C-, Q- or R-orders: \begin{equation}\tag{$C$} \lim \frac…
