The norm of a canonical isomorphism of determinant line bundles

Thesis

We extend an involution formula given by a canonical isomorphism of determinant line bundles in Rössler’s [a] to the analytic case where the determinant of cohomology is endowed with the Quillen metric, in the case where the fixed point scheme is a Cartier divisor.

Additionally, we show the relation between Rössler’s main results in [a] and the Adams-Riemann-Roch theorem; and we extend the main result of Ducrot’s [b], which aims to extend Deligne’s pairing to the higher relative dimensional intersection bundle, to the analytic case.
