%0 Journal Article %T Derived equivalences of Calabi-Yau fibrations %A Cristina Martinez Ramirez %A Andrey Todorov %J Mathematics %D 2009 %I arXiv %X We consider fibrations by abelian surfaces and K3 surfaces over a one dimensional base that are Calabi-Yau and we obtain dual fibrations that are derived equivalent to the original fibration. Finally, we relate the problem to mirror symmetry. %U http://arxiv.org/abs/0901.0509v5
