For a radical square zero algebraΛand an indecomposable rightΛ-module M,whenΛis Gorenstein of finite representation type orτM isτ-rigid,M isτ-rigid if and only if the first two projective terms of a minimal projective resolution of M have no non-zero direct summands in common.In particular,we determine allτ-tilting modules for Nakayama algebras with radical square zero.
