Abstract: Let ${mathbb F}_q$ be the finite field of $q$ elements and $k$ be its algebraic closure. Let $Q$ be a quiver with automorphism $sigma$. In this survey we focus on the study of modules over the ${mathbb F}_q$-algebra ${frak A}(Q,sigma;q)$ associated with the pair $(Q,sigma)$ in terms of $F$-stable representations of $Q$ over $k$, and we also discuss several polynomials obtained by counting numbers of indecomposable ${frak A}(Q,sigma;q)$-modules. In case $Q$ is a tame quiver, we present the formula for the number of isoclasses of indecomposable ${frak A}(Q,sigma;q)$-modules with a fixed dimension vector.
Keywords: quiver with automorphism,hereditary algebra, representation
