This paper classifies Hermitian structures on 6-dimensional nilmanifolds $M = \Gamma\G$ for which the fundamental 2-form is $\partial \overline \partial$-closed, a condition that is shown to depend only on the underlying complex structure J of M. The space of such J is described when G is the complex Heisenberg group, and explicit solutions are obtained from a limacon-shaped curve in the complex plane. Related theory is used to provide examples of various types of Ricci-flat structures.

Abstract
This paper classifies Hermitian structures on 6-dimensional nilmanifolds $M = \Gamma\G$ for which the fundamental 2-form is $\partial \overline \partial$-closed, a condition that is shown to depend only on the underlying complex structure J of M. The space of such J is described when G is the complex Heisenberg group, and explicit solutions are obtained from a limacon-shaped curve in the complex plane. Related theory is used to provide examples of various types of Ricci-flat structures.File in questo prodotto:
