$n$-quivers and A Universal Investigation of $n$-representations of Quivers (1604.05801v4)

Abstract: We have two parallel goals of this paper. First, we investigate and construct cofree coalgebras over $n$-representations of quivers, limits and colimits of $n$-representations of quivers, and limits and colimits of coalgebras in the monoidal categories of $n$-representations of quivers. Second, we introduce a generalization for quivers and show that this generalization can be seen as essentially the same as $n$-representations of quivers. This is significantly important because it allows us to build a new quiver $\mathscr{Q}{!{(\Qq_1, \Qq_2,..., \Qq_n)}}$, called $n$-quiver, from any given quivers $\Qq_1,\Qq_2,...,\Qq_n$, and enable us to identify each category $Rep_k(\Qq_j)$ of representations of a quiver $\Qq_j$ as a full subcategory of the category $Rep_k(\mathscr{Q}{!{(\Qq_1, \Qq_2,..., \Qq_n)}})$ of representations of $\mathscr{Q}{!{(\Qq_1, \Qq_2,..., \Qq_n)}}$ for every $j \in {1,\,\,2,\,\,..., \,\,n}$.
