An extension problem related to the fractional Branson-Gover operators
Jan Frahm, Bent Ørsted, Genkai Zhang
The Branson-Gover operators are conformally invariant differential operators of even degree acting on differential forms. They can be interpolated by a holomorphic family of confor…

Holomorphic torsion and geometric zeta functions for certain Hermitian locally symmetric manifolds
Henri Moscovici, Robert J. Stanton, Jan Frahm
We give a dynamical description, in terms of a Weil-type zeta function, to the holomorphic torsion with coefficients for certain compact Hermitian locally symmetric manifolds, whos…
