Boundedness of the Images of Period Maps

Abstract

We prove a conjecture of Griffiths on simultaneous normalization of all periods which asserts that the image of the lifted period map on the universal cover lies in a bounded domain in complex Euclidean space.

The original proof in this paper contains an error. A corrected version has been posted separately as arXiv:2602.13947. This withdrawal is made to prevent confusion and to direct readers to the revised paper
