Quasi-projective Moduli for Polarized Manifolds
Springer Berlin (Verlag)
978-3-642-79747-7 (ISBN)
The subject of the book are construction techniques for classifying spaces of projective manifolds and positivity results for direct image sheaves. Both together allow the proof of the central result, the existence of quasi-projective moduli schemes for a large class of manifolds. The book is of great interest for researchers and graduate students in algebraic geometry or number theory.
