On a B-field transform of generalized complex structures over complex tori
Let be a mirror pair of an n-dimensional complex torus and its mirror partner . Then, by SYZ transform, we can construct a holomorphic line bundle with an integrable connection from each pair of a Lagrangian section of and a unitary local system along it, and those holomorphic line bundles with integrable connections form a dg-category . In this paper, we focus on a certain B-field transform of the generalized complex structure induced from the complex structure on , and interpret it as the deformation of by a flat gerbe . Moreover, we construct the deformation of associated to the deformation from to , and also discuss the homological mirror symmetry between and its mirror partner on the object level.
期刊介绍:
The Journal of Geometry and Physics is an International Journal in Mathematical Physics. The Journal stimulates the interaction between geometry and physics by publishing primary research, feature and review articles which are of common interest to practitioners in both fields.
The Journal of Geometry and Physics now also accepts Letters, allowing for rapid dissemination of outstanding results in the field of geometry and physics. Letters should not exceed a maximum of five printed journal pages (or contain a maximum of 5000 words) and should contain novel, cutting edge results that are of broad interest to the mathematical physics community. Only Letters which are expected to make a significant addition to the literature in the field will be considered.
The Journal covers the following areas of research:
Methods of:
• Algebraic and Differential Topology
• Algebraic Geometry
