Deformed Hyperkähler Structure for K3 Surfaces
Chang-Yeong Lee
Abstract
We apply the method of algebraic deformation to N-tuple of algebraic K3 surfaces. When N=3, we show that the deformed triplet of algebraic K3 surfaces exhibits a deformed hyperkähler structure. The deformation moduli space of this family of noncommutatively deformed K3 surfaces turns out to be of dimension 57, which is three times of that of complex deformations of algebraic K3 surfaces.
