On the classification of twisting maps between $K^n$ and $K^m$

Abstract

We define the notion of admissible pair for an algebra $A$, consisting on a couple $(\Gamma ,R)$, where $\Gamma$ is a quiver and $R$ a unital, splitted and factorizable representation of $\Gamma$, and prove that the set of admissible pairs for $A$ is in one to one correspondence with the points of the variety of twisting maps ${\mathcal{T}}_A^n:=\mathcal{T}(K^n,A)$. We describe all these representations in the case $A=K^m$.
