Twistors, Hyper-Kähler manifolds, and complex moduli

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

A theorem of Kuranishi (Ann Math 75(2):536–577, 1962) tells us that the moduli space of complex structures on any smooth compact manifold is always locally a finite-dimensional space. Globally, however, this is simply not true; we display examples in which the moduli space contains a sequence of regions for which the local dimension tends to infinity. These examples naturally arise from the twistor theory of hyper-Kähler manifolds.
