Gluing formulas for determinants of Dolbeault laplacians on Riemann
surfaces
We present gluing formulas for zeta regularized determinants of
Dolbeault laplacians on Riemann surfaces. These are expressed in
terms of determinants of associated operators on surfaces with
boundary satisfying local elliptic boundary conditions. The
conditions are defined using the additional structure of a framing,
or trivialization of the bundle near the boundary. An application
to the computation of bosonization constants follows directly from
these formulas.
