Twisted Fourier-Mukai transforms and bundles on non-Kähler elliptic surfaces

Abstract

In this paper, we study holomorphic rank-2 vector bundles on non-Khler elliptic surfaces. Our main tool for analysing these bundles is of course the spectral cover. However, given the non-Khler condition, the elliptic surfaces we are considering do not have sections and gerbes naturally arise in this context. The spectral construction presented in this paper is a modification of the Fourier-Mukai transform for elliptic fibrations without a section. After examining some of the properties of this Fourier-Mukai transform, we give a complete classification of vector bundles on these surfaces.
