A bstract We introduce a systematic approach to constructing\(\mathcal {N}\)= 1 Lagrangians
for a class of interacting\(\mathcal {N}\)= 2 SCFTs. We analyse in detail the simplest case of …

This mini-course, conducted at the XI School on Geometric, Algebraic, and Topological
Methods in Quantum Field Theory held in Villa de Leyva, Colombia, provides an overview of …

We derive a formula for D3-brane charge on a compact spacetime, which includes torsion
corrections to the tadpole cancellation condition. We use this to classify D-branes and …

In this note, we present a scenario in which the existence of dS vacua is jeopardized by
topological transitions between non-BPS branes and fluxes in type IIB toroidal …

Wrap m D5-branes around the 2-cycle of a conifold, place n D3-branes at a point and watch
the system relax. The D5-branes source m units of RR 3-form flux on the 3-cycle, which …

By wrapping D 3-branes over 3-cycles on a half-flat manifold, we construct an effective
supersymmetric black hole in the N= 2 low-energy theory in four dimensions. Specifically …

We introduce a systematic approach to constructing N= 1 Lagrangians for a class of
interacting N= 2 SCFTs. We analyse in detail the simplest case of the construction, arising …

A classification of D-branes in Type IIB Op− orientifolds and orbifolds in terms of Real and
equivariant KK-groups is given. We classify D-branes intersecting orientifold planes from …

In this work we study the generalization of twisted homology to geometric and nongeometric
backgrounds. In the process, we describe the necessary conditions to wrap a network of D …
