Some Inequalities for Kodaira-Iitaka Dimension on Subvarieties
arXiv:0910.4235
Abstract
This paper generalizes the easy addition formula. Given a normal variety with an invertible sheaf , inequalities are found bounding $\ka(X,L)$ from above based on the behavior of restricted to a subvariety or to a pair of "positive" intersecting subvarieties.
