"WebA typical cDV singularity is a one-parameter deformation of a rational double point. A terminal threefold singularity is a cyclic quotient of an isolated cDV singularity. Say X ′ → X is such that X ′ has cDV singularities. Suppose we already know the statement for cDV singularities. Let Y ″ denote a resolution of Y ′ = X ′ × X Y. " - Cdv singularity
