On universal deformation rings of modules over a certain class of symmetric algebras of representation finite type

Let 𝕜 be an algebraically closed field. Recently, K. Erdmann classified the symmetric 𝕜-algebras Λ of finite representation type such that every non-projective module M has period dividing four. The goal of this paper is to determine the indecomposable modules M over these class of algebras Λ whose stable endomorphism ring is isomorphic to 𝕜, and then calculate their corresponding universal deformation rings (in the sense of F. M. Bleher and the third author).
