This year, the world mathematical community recalls the memory of Abraham Robinson (1918–1984), an outstanding scientist whose contributions to delta-wing theory and model theory

Recently, a new FETI approach for two-dimensional problems was introduced in [16, 17, 33], where the continuity of the finite element functions at the cross points is retained in

On the other hand, from physical arguments, it is expected that asymptotically in time the concentration approach certain values of the minimizers of the function f appearing in

In section 2 we present the model in its original form and establish an equivalent formulation using boundary integrals. This is then used to devise a semi-implicit algorithm

The purpose of this paper is analyze a phase-field model for which the solid fraction is explicitly functionally dependent of both the phase-field variable and the temperature

In addition, we extend the methods and present new similar results for integral equations and Volterra- Stieltjes integral equations, a framework whose benefits include the

As for the long time behavior of solutions for the micropolar fluid flows on unbounded domain, Dong and Chen [7] investigated the existence and regularity of the global attractors in
