Abstract:
To a pair of normal functions on a complex manifold U one can associate a canonically metrized line bundle (B, h).If U is Zariski open in a complex manifold S one can ask two natural questions:
a) Is there a canonical choice of extension of B to a line bundle on S?
b) Does the metric h extend to a metric on S?
For normal functions which are admissible in the sense of M. Saito, in joint work with P. Brosnan, we give a positive answer to (a) and determine an obstruction to (b) which can be expressed as a pairing on intersection cohomology.
