Las dinámicas de colaboración científica visualizan la relación entre investigadores, instituciones y países, determinando estructuras de comunidades científicas. El estudio tuvo como objetivo analizar las dinámicas de publicación a través de …

In this paper we are interested in studying the properties of Armendariz, Baer, quasi-Baer, p.p. and p.q.-Baer over skew PBW extensions. Using a notion of compatibility, we generalize several propositions established for Ore extensions and present …

The objective of this paper is to investigate the ascending chain condition on principal left (resp. right) ideals of noncommutative rings known as skew PBW extensions. We consider these extensions over domains and over Sigma-rigid rings. We unify …

In this paper we are concerned with the Hölder regularity of weak solutions of the Cauchy problem for the general degenerate parabolic equations in (1). By using the vanishing viscosity method and the maximun principle some explicit Hölder exponent …

Esta investigación se centra en mostrar una panorámica sobre la formación científica de las mujeres en Colombia. Para este propósito, se relacionaron algunos referentes teóricos usados para llevar a cabo el estudio de la historia de la matemática en …

In this paper, k-linear representations of posets are used to define lattice-based schemes of visual cryptography for color images.

The aim of this paper is to investigate a general notion of 𝜎-PBW extensions over Armendariz rings. As an application, the properties of Baer, quasi-Baer, p.p., and p.q.-Baer are established for these extensions. We generalize several results in the …

In this paper, we show that the tensor product of skew PBW extensions is a skew PBW extension. We also characterize the enveloping algebra of a skew PBW extension. Finally, we establish conditions for sufficiency to guarantee the property of being …

En el artículo se presenta un análisis epistemológico sobre la evolución histórica del objeto Grupo según la visión de Piaget y García. En esta dirección, se describen unos mecanismos en el proceso evolutivo de dicho objeto matemático que parten de …

A categorification in the sense of Ringel and Fahr is given to the sequences A016116 and A000034 in the OEIS by using t-orbits in the Auslander-Reiten quiver of some Dynkin algebras.
