ON THE REPRESENTATION TYPE OF CERTAIN TRIVIAL EXTENSIONS
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 modu...

| Sumario: | 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 |
