Abstract: In this talk I will present a class of singular fibrations called boundary Lefschetz fibrations. These play important roles in the, quite different, fields of semi-toric and generalized complex geometry. After describing how they can be studied using Lie algebroids, I willshow that they behave well with respect to blow-ups and connected sums. Finally, I will show how they can be used in extending T-duality, a version of mirror symmetry. Joint work with Gil Cavalcanti and Ralph Klaasse.
