This note introduces a method for crafting isolated symplectic singularities, suggesting connections to fundamental group theories.
Recently, Bellamy et al. constructed an infinite series of four‐dimensional isolated symplectic sngularities with trivial local fundamental group, inspired by a question of Beauville. In this short note, we introduce an easy construction of isolated symplectic singularities (of any dimension) with trivial local fundamental group. We will use a toric hyperkähler construction.
