抄録: This work is motivated by the canonical model of degenerations of Riemann surfaces. For a quotient space Ad−1/Γ of a 'multiplicative'A-singularity Ad−1 in Cn+1 under a certain cyclic group action Γ on Ad−1, we explicitly construct a small finite abelian subgroup G of GL(n, C) such that Ad−1/Γ ∼= Cn/G. A resolution of Cn/G gives a decomposition of the monodromy (a higher-dimensional fractional Dehn twist) of a degeneration Ad−1/Γ → C into subtwists along the exceptional set (it seems that T. Ashikaga’s work on resolutions is related to this). Moreover: (1) We give a numerical criterion for a certain subgroup of GL(n,C) to be small. (2) For a certain family of subgroups of GL(n, C), we show that if one subgroup of this family is small, then all subgroups of this family are small (equi-smallness theorem).2016-06-24T00:00:00ZHorocycle flows without minimal sets
