This paper is devoted to the study of nonlinear homogeneous Dirichlet boundary p(u)-laplacian problem. Existence, uniqueness and structural stability results of weak solutions are obtained by approximation method and convergent sequences in terms of Young... see more

We consider the smallest subring D of R(X) containing every element of the form 1/(1+x2), with x ? R(X). D is a Prüfer domain called the minimal Dress ring of R(X). In this paper, addressing a general open problem for Prüfer non Bézout domains, we investi... see more

Time discretizations of phase-field systems have been studied. For example, a time discretization and an error estimate for a parabolic-parabolic phase-field system have been studied by Colli--K. [Commun. Pure Appl. Anal. 18 (2019)]. Also, a time discreti... see more

In this paper, the Dunkl-semiclassical orthogonal polynomials will be studied as a generalization ofthe Dunkl-classical ones. We obtain some characterizations for such polynomials.  Moreover, an example of non-symmetric Dunkl-semiclassical ortho... see more

Certain theorems of existence, non-existence and uniqueness for boundary value problems modeling axial symmetric problems in general relativity are presented using the Weyl's metric. A solution related to the classical Poiseuille solution of non-relativis... see more

The family of partial differential equations -?4u-e?8u = 0 (e > 0) is studied in a bounded domain O for given boundary data. We show that for each e > 0 the problem has a unique viscosity solution which is exactly the (4+e)-harmonic map with the giv... see more

Given a real algebraic curve, embedded in projective space, we study the computational problem of deciding whether there exists a hyperplane meeting the curve in real points only. More generally, given any divisor on such a curve, we may ask whether the c... see more

We study a class of semialgebraic convex bodies called discotopes. These are instances of zonoids, objects of interest in real algebraic geometry and random geometry. We focus on the face structure and on the boundary hypersurface of discotopes, highlight... see more

This work is concerned with the dynamics of a polymerization process coupled with mass transfer and monomers injection, modeled by means of an infinite-dimensional system of Smoluchowski's equations in a finite graph. Under suitable assumptions on the sys... see more
