Titolo: On general type varieties admitting global holomorphic forms

Abstract: For all nonsingular projective n-folds V of general type, we
prove the existence of Noether type inequalities in the following form:
vol(V)\geq a_{n,k}h^0(\Omega_V^k)-b_{n,k}
where 0< k\leq n, a_{n,k} and b_{n,k} are positive constants only depending
on n and k. As applications, we determine the minimal volume for 3-folds of
general type with \chi(\mathcal{O})\neq 2,3 and disclose a new type of
lifting principles for the sequence of canonical stability indices for
varieties of general type. Finally we prove a theorem about ``strong
lifting principle'' on varieties X of general type with q>dim(X).This is
based on a joint work with Zhi Jiang.

Tutti gli interessati sono invitati a partecipare.
