SUMMARY:Yang-Hui He (City\, University of London)
DESCRIPTION:Calabi-Yau Volumes and Reflexive Polytopes\nWe study various geometrical quantities for Calabi-Yau varieties realized as cones over Gorenstein Fano varieties\, obtained as toric varieties from reflexive polytopes in various dimensions. Focus is made on reflexive polytopes up to dimension 4 and the minimized volumes of the Sasaki-Einstein base of the corresponding Calabi-Yau cone are calculated. By doing so\, we conjecture new bounds for the Sasaki-Einstein volume with respect to various topological quantities of the corresponding toric varieties. We give interpretations about these volume bounds in the context of string theory. \nThis is based on joint work with Rak-Kyeong Seong and Shing-Tung Yau.
