摘要：We consider the rigidity dimension of algebras, a new homological dimension introduced recently by Chen, Fang, Kerner, Koenig and Yamagata, and give explicit formulae for the rigidity degrees of indecomposable modules over representation-finite self-injective algebras of type ADE. Surprisingly, the combinatorics turn out to be closely related to the classic Euclidean algorithm. This is a joint work with Xiaojuan Yin.
