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

5 years ago

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

5 years ago

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

5 years ago

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*?

We survey the convergence orders of sequences and show the orders of the basic iterative sequences for solving nonlinear equations…

Kantorovich type operators associated with Jain-Markov operators

5 years ago

AbstractThis note focuses on a sequence of linear positive operators of integral type in the sense of Kantorovich. The construction…

Asymptotic analysis of a structure-preserving integrator for damped Hamiltonian systems
