On the behaviour of the solution to a viscoplastic contact problem
Abstract The present paper represents a continuation of [2]. There, a quasistatic contact problem for viscoplastic materials was considered, in…
Marangoni and gravity flows in thin liquid layers
Abstract The paper presents a comparison between the experimental and caculated data for the Marangoni-type flow, in competition with the…

On the long time energy conservation by high order geometric integrators
Abstract The main aim of this paper is to investigate the long-time behavior of three high order geometric integrators, namely…
Stable spectral collocation solutions to Cauchy problems for nonlinear dispersive wave equations
Abstract In this paper we are concerned with accurate and stable spectral collocation solutions to initial-boundary value problems attached to some challenging…
Sufficient convergence conditions for certain accelerated successive approximations
Abstract We have recently characterized the q-quadratic convergence of the perturbed successive approximations. For a particular choice of the parameters, these…
