In this communication, the proof of the following theorem is sketched: IfD 1 is a bounded domain in Cn with real analytic boundary whose ∂̄-Neumann problem is globally real analytic hypoelliptic andf is a proper holomorphic mapping ofD 1 onto a second bounded domainD 2 in Cn with real analytic boundary, then the mappingf extends to be holomorphic in a neighborhood of ¯D1 . The proof relies on a transformation formula for the Bergman projection under proper holomorphic mappings.
