Abstract
We show that a tame quasi-tilted algebra A (over an algebraically closed field) is simply connected if and only if its first Hochschild cohomology group (with coefficients in the biomodule AAA) vanishes. We also classify these algebras, and give characterisations of those tame quasi-tilted algebras which are strongly simply connected.
