On almost simple transcendental field extensions
ANTONIO GONZALEZ FERNANDEZ; RODRIGO JIMENEZ CORREA; JESUS EFREN PEREZ TERRAZASWe study some properties of almost simple transcendental field extensions in order to analyze the endomorphisms ring of algebraically bounded Λ−modules where Λ is a semigenerically tame finite-dimensional k−algebra, k a ... -
On centrally generically tame algebras over perfect fields
RAYMUNDO BAUTISTA RAMOS; JESUS EFREN PEREZ TERRAZAS; LEONARDO SALMERON CASTROWe show that the central generic tameness of a finite-dimensional algebra Λover a (possibly finite) perfect field, is equivalent to its non-almost sharp wildness. In this case: we give, for each natural number d, ... -
On permutation polynomials over local finite commutative rings
JAVIER ARTURO DIAZ VARGAS; JOSE ANTONIO SOZAYA CHANIn this paper, we give criteria for a polynomial to be a permutation polynomial of a local finite commutative ring with identity. These criteria generalize known results established for finite fields. On the other hand, ... -
On restrictions of generic modules of tame algebras
RAYMUNDO BAUTISTA RAMOS; JESUS EFREN PEREZ TERRAZAS; LEONARDO SALMERON CASTROGiven a convex algebra Λ0 in the tame finite-dimensional basic algebra Λ, over an algebraically closed field, we describe a special type of restriction of the generic Λ-modules. -
On semigeneric tameness under base field extension
JESUS EFREN PEREZ TERRAZASThe notions of central endolength and semigeneric tameness are introduced, and their behaviour under base field extension for finite-dimensional algebras over perfect fields are analysed. For k a perfect field, K an ... -

On the connection between the representation type of an algebra and its lattice of preradicals
JESUS EFREN PEREZ TERRAZASIn this paper, we study lattices of preradicals which are not small classes (in which case we say that the corresponding rings are p-large), and specially we consider some infinite representation type algebras. We construct ... -

On the geometry of null hypersurfaces in Minkowski space
JOSE MATIAS NAVARRO SOZA; OSCAR ALFREDO PALMAS VELASCO; DIDIER ADAN SOLIS GAMBOAThe present work is divided into three parts. First we study the null hypersurfaces of the Minkowski space R1n+2, classifying all rotation null hypersurfaces in R1n+2. In the second part we start our analysis of the ... -

On the number of lines in the limit set for discrete subgroups of PSL(3, C)
WALDEMAR DEL JESUS BARRERA VARGAS; ANGEL CANO CORDERO; JUAN PABLO NAVARRETE CARRILLOGiven a discrete subgroup G ⊂ PSL(3, C), acting on the complex projective plane, P2C , in the canonical way, we list all possible values for the number of complex projective lines and for the maximum number of complex ... -
