Streszczenie
Let $A$ be a finite-dimensional algebra over an algebraically closed field. The algebra $A$ is called locally hereditary if any local left ideal of $A$ is projective. We give criteria, in terms of the Tits quadratic form, for a locally hereditary algebra to be of tame representation type. Moreover, the description of all representation-tame locally hereditary algebras is completed.
