An explicit description of the colored mutation class of $A_{n}$ -quivers

Viviana Gubitosi, Pablo Rosero

This paper addresses the combinatorial structure of $m$ -colored mutation classes. We provide an explicit and purely combinatorial description of the $m$ -colored quivers that arise…

Some remarks about $F P_{n}$ -projective and $F P_{n}$ -injective modules

Viviana Gubitosi, Rafael Parra

Let $R$ be a ring. In \cite{MD4} Mao and Ding defined an special class of $R$ -modules that they called $ FP_n $-projective $R$ -modules. In this paper, we give some new characteri…

The coloured mutation class of $A_{n}$ quivers

Viviana Gubitosi, Claudio Qureshi, Rafael Parra

In this paper we give an explicit and pure combinatorial description of the $m$ -coloured quivers that appears in the $m$ -coloured mutation class of a quiver of type $A_{n}$ .…

On the non-existence of perfect codes in the Niederreiter-Rosenbloom-Tsfasman metric

Viviana Gubitosi, Aldo Portela, Claudio Qureshi

In this paper we consider codes in $F_{q}^{s \times r}$ with packing radius $R$ regarding the NRT-metric (i.e. when the underlying poset is a disjoint union of chains with th…

Finiteness properties and homological dimensions of Skew Group rings

Viviana Gubitosi, Rafael Parra

Let $G$ be a finite group acting on a ring $R$ and $H$ a subgroup of $G$ . In this paper we compare some homological dimensions over the skew group rings $R G$ and $R H$ . Moreover, un…
