F-theory on singular spaces

Andrés Collinucci (Physique Théorique et Mathématique and International Solvay Institutes, Université Libre de Bruxelles, C.P. 231, 1050, Bruxelles, Belgium) ; Raffaele Savelli (Institut de Physique Théorique, CEA Saclay, Orme de Merisiers, F-91191, Gif-surYvette, France)

We propose a framework for treating F-theory directly, without resolving or deforming its singularities. This allows us to explore new sectors of gauge theories, including exotic bound states such as T-branes, in a global context. We use the mathematical framework known as Eisenbud’s matrix factorizations for hypersurface singularities. We display the usefulness of this technique by way of examples, including affine singularities of both conifold and orbifold type, as well as a class of full-fledged compact elliptically fibered Calabi-Yau fourfolds.
