<p>This paper introduces Auslander-Reiten Sequences in mod A, where A is a finite dimensional -algebra. We will also introduces almost split morphism, as a special form of morphisms, which will provide a natural way to present the form of Auslander-Reiten sequences. These sequences are particulary useful in representation theory of algebras.</p><p>Key words:<strong> </strong>almost split morphisms, , irreducible morphisms, almost split sequences </p>
