Аннотация

An extremal curve germ is the analytic germ of a threefold with terminalsingularities along a reduced complete curve admitting a contraction whosefibres have dimension at most one. The aim of the present paper is to reviewthe results concerning contractions whose central fibre is irreducible andcontains only one non-Gorenstein point.
