Title: Faltings heights and a non-abelian Chowla-Selberg formula for CM abelian varieties

Abstract: In this talk we will give an identity which evaluates Faltings heights of CM abelian varieties with complex multiplication by non-abelian CM fields in terms of values of the Barnes multiple Gamma function at algebraic numbers. This identity can be seen as a non-abelian Chowla-Selberg formula for CM abelian varieties. The proof uses recent joint work with Riad Masri and Frank Thorne on the Colmez conjecture. This is joint work with Riad Masri and Wei Lun Tsai.
