## CYMS Seminar - Oswaldo Sevilla

### Thursday, November 14th, 2019

**Time:** 2:30 p.m ** Place:** Jeffery Hall 319

**Speaker:** Oswaldo Sevilla (Fields Institute and Centro de Investigacion en Matematicas A.C.)

**Title:** Calabi Yau Threefolds arising from certain root lattices.

**Abstract:** I'll show my work on the construction of Calabi Yau threefolds that are constructed from the C_3 and C_4 root systems, using a construction by H. Verrill (Root lattices and pencils o f varieties, 1996) based on a paper of V. Batyrev (Dual Polyhedra and mirror symmetry for Calabi-Yau hypersurfaces in toric varieties,1994).
