We show that a tame quasi-tilted algebra A (over an algebraically closed รฟeld) is simply connected if and only if its รฟrst Hochschild cohomology group (with coe cients in the biomodule AAA) vanishes. We also classify these algebras, and give characterisations of those tame quasi-tilted algebras whic
