A viscoelastic contact problem with adhesion and surface memory effects
AbstractWe consider a mathematical model which describes the quasistatic contact between a viscoelastic body and an obstacle, the so-called foundation.…
Geophysical implications of a decentered inner core
AbstractIn a first approximation, the Earth’s interior has an isotropic structure with a spherical symmetry. Over the last decades the…
On the accuracy of pseudospectral differentiation
AbstractFor various grids on a finite interval we measure the accurarcy of pseudospectral (collocation) differentiation matrices using two parameters. The…
Accurate spectral solutions to a phase-field transition system
AbstractThe paper is mainly concerned with numerical approximation of solutions to the phase-field transition system (Caginalp’s model), subject to the…
Diffusion in random velocity fields with applications to contaminant transport in groundwater
AbstractThe process of diffusion in a random velocity field is the mathematical object underlying currently used stochastic models of transport in…
Intrinsic superstatistical components of financial time series
AbstractTime series generated by a complex hierarchical system exhibit various types of dynamics at different time scales. A financial time…
