On a series of Gorenstein cyclic quotient singularities admitting a unique projective crepant resolution

Dimitrios I. Dais, Martin Henk

In this paper we prove that the Gorenstein cyclic quotient singularities of type \frac 1l (1,..., 1,l-(r-1)) with $l\ge r\ge 2$, have a \textit{unique}torus-equivariant projectiv…
