Conformally covariant bi-differential operators for differential forms

Salem Ben Saïd, Jean-Louis Clerc, Khalid Koufany

The classical Rankin-Cohen brackets are bi-differential operators from $C^{\infty} (R) \times C^{\infty} (R)$ into $C^{\infty} (R)$ . They are covariant for the (diag…

The symplectic area of a geodesic triangle in a Hermitian symmetric space of compact type

Mads Aunskjær Bech, Jean-Louis Clerc, Bent Ørsted

Let $M$ be an irreducible Hermitian symmetric space of compact type, and let $ω$ be its Kähler form. For a triplet $(p_{1}, p_{2}, p_{3})$ of points in $M$ we study conditions under which…
