On NI and NJ skew PBW extensions
Héctor Suárez, Andrés Chacón, Armando Reyes
We establish necessary or sufficient conditions to guarantee that skew Poincaré-Birkhoff-Witt extensions are NI or NJ rings. Our results extend those corresponding for skew polynom…
Two blocks connected by a string with variable tension: A dynamic case
H. J. Herrera Suárez, M. Machado - Higuera, J. H. Muñoz
In this paper, the dynamic case of a system made up of two blocks connected by a string over a smooth pulley is revisited. One mass lies on a horizontal surface without friction, a…
Symmetry in the system conformed by two blocks connected by a string with variable tension
D. Benitez, H. J. Herrera Suárez, J. H. Muñoz
In this paper we review the system made up by two blocks connected by a string over a smooth pulley with variable tension. One block lies on an horizontal surface and the another b…
Double Ore extensions versus graded skew PBW extensions
James Yair Gómez, Héctor Suárez
In this paper we present necessary and sufficient conditions for a graded (trimmed) double Ore extension to be a graded (quasi-commutative) skew PBW extension. Using this fact, we…
Skew PBW extensions over weak symmetric and -weak symmetric rings
Armando Reyes, Héctor Suárez
In this paper we study skew Poincaré-Birkhoff-Witt extensions over weak symmetric and -weak symmetry rings. Since these extensions generalize Ore extensions of injective typ…
Skew Poincaré-Birkhoff-Witt extensions over weak -rigid rings
Armando Reyes, Héctor Suárez
In this paper we introduce the notion of weak -rigid ring which extends -rigid rings and -rigid rings defined for Ore extensions and skew PBW extensions, respectively. We…
