Title: Vanishing criteria for tautological systems
Abstract: Tautological systems are vast generalizations of AA-hypergeometric systems to the case of an arbitrary reductive algebraic group. Much of the interest in such systems has come from their application to period integrals of Calabi-Yau hypersurfaces. As with AA-hypergeometric systems, part of the input data is a parameter ββ. I will discuss joint work with P. Gorlach, T. Reichelt, C. Sevenheck, and U. Walther discussing criteria which bounds the number of parameters ββ which give a non-trivial tautological system.
