In this paper we deal with the operator defined as 𝑓(∂,𝛼)𝜙:=−1𝜉→𝑥(|𝑓(𝜉)|𝛼𝑝𝑥→𝜉𝜙), where f(ξ) is an elliptic quadratic form of dimension 3 over ℚ p . We study the Cauchy problem associated that operator, and find the fundamental solution and some …
Some authors have studied relations between Artin-Schelter regular algebras, N-Koszul algebras and Calabi- Yau algebras (resp. skew Calabi-Yau) of dimension d. In this paper we want to show through examples and counterexamples some relations between …
We investigate the large time behavior of the global weak entropy solutions to the symmetric Keyfitz-Kranzer system with linear damping. It is proved that as t to infinity the entropy solutions tend to zero in the Lp norm.
Este trabajo tiene como objetivo caracterizar la tendencia de las publicaciones científicas en Colombia en el área de Matemáticas reportadas en la base de datos Web of Science-Wok, en el periodo 2001 a 2012, de autores con afiliación institucional …
Esta investigación tuvo como objeto evaluar la influencia de las tecnologías de la información y la comunicación, TIC, en el proceso de enseñanza - aprendizaje de conceptos básicos de electrónica analógica en grado séptimo del Colegio Andino de …
En este trabajo revisamos algunos conceptos básicos relacionados al cálculo numérico de soluciones de ecuaciones diferenciales parciales. En particular, aplicamos el método de (los) elementos finitos al cálculo de auto-valores y auto-funciones de …
We study the one-dimensional Riemann problem for a hyperbolic system of three conservation laws of Temple class. This system is a simplification of a recently proposed system of five conservations laws by Bouchut and Boyaval that model viscoelastic …
In this article we study the Cauchy problem for a new class of parabolic-type pseudodifferential equations with variable coefficients for which the fundamental solutions are transition density functions of Markov processes in the four dimensional …
In this article we study the problem of first return associated to an elliptic pseudodifferential operator with non-radial symbol of dimension 3 over the p-adics.
This article aims to present the Hilbert’s Basis Theorem for an skew polynomials ring, some classes of ideals that are defined in this ring, and the neccesary conditions for an skew polynomials ring to be semiprimitive. Moreover, some examples for …
