Speaker: Thorsten Schimannek, Utrecht UniversityTitle: M-theory on nodal Calabi-Yau 3-folds and torsion refined GV-invariantsAlgebraic Geometry in String Theory Seminar Speaker: Thorsten Schimannek (Utrecht University) Title: M-theory on nodal Calabi-Yau 3-folds and torsion refined GV-invariants Abstract: The physics of M-theory and Type IIA strings on a projective nodal CY 3-folds is determined by the geometry of a small resolution, even if the latter is not Kähler. We will demonstrate this explicitly in the context of a family of Calabi-Yau double covers of P^3. Using conifold transitions, we prove that the exceptional curves in any small resolution are torsion while M-theory develops a discrete gauge symmetry.This leads to a torsion refinement of the ordinary Gopakumar-Vafa invariants, that is associated to the singular Calabi-Yau and captures the enumerative geometry of the non-Kähler resolutions. We further argue that... |

Speaker: Justin Moore, Cornell UniversityTitle: Homology, higher derived limits, and set theoryColloquium Speaker: Justin Moore (Cornell University) Title: Homology, higher derived limits, and set theory Abstract: Singular homology has a number of well-known defects when used to study spaces such as the Hawaiian earring and solenoids. It may not reflect the "shape" of the space and can give counterintuitive information about its dimension. One remedy of this is to develop a homology theory based on approximating spaces by polyhedra, computing their homologies, and then taking a limit. This is the approach taken by Steenrod-Sitnikov homology and Lisica and Mardesic's strong homology. Even within the class of locally compact second countable spaces though, the properties of these homology theories -- and the higher derived limits which underly them -- are dependent on... |
