Abstract: A nonlinear parabolic problem is solved by a linear approximation scheme using a nonstandard time discretization with a relaxation function. The relaxation function is determined by ...

Abstract: This article considers the wide-spacing approximation when applied to two-dimensional linear problems involving the scattering and radiation of water waves by structures in a fluid of ...

ABSTRACT: The Einstein ring is usually explained in the framework of the gravitational lens. Conversely here we apply the framework of the expansion of a superbubble (SB) in order to explain the ...

ABSTRACT: We review the distance modulus in twelve different cosmologies: the ΛCDM model, the wCDM model, the Cardassian model, the flat case, the ?CDM cosmology, the Einstein—De Sitter model, the ...
