Automorphism groups on smooth cubic surfaces were determined by B.Segre (1942), T.Hosoh (1997) and so forth. On the other hand, J.W.Bruce and C.T.C.Wall (1979) classified normal singular cubic surfaces, by modern singularity terminology using the Dynkin diagram. According to type of
singularities, automorphism groups on normal singular cubic surfaces with no parameters were
determined in my master thesis (2006). In this seminar, we present a method for the determination of automorphism groups on normal singular cubic surfaces with parameters according to type of singularities, and we release the results obtained.
