Resumen de On the representation type of certain trivial extensions

Cristian Novoa Bustos, José Antonio de la Peña

• Let A ∼= kQ/I be a basic and connected finite dimension algebra over closed field k. In this note show that in case B = A[M] is a tame one-point extension of a tame concealed algebra A by an indecomposable module M, then the trivial extension T(B) = B ∝ DB is tame if and only if the module M is regular.
