Abstract

In this dissertation, we describe a paper that improves on the conditions that imply holomorphic curves and integral points are degenerate or not Zariski-dense. Specifically, we show that for a holomorphic curve into a projective variety of dimension n intersecting q divisors in subgeneral position whose sum is equidegreelizable, if q is greater than or equal to n 2 , then the curve is degenerate. This is an improvement from 2n 2 under the same conditions in paper. To achieve this result, we borrow methods from that combine divisors in pairs and uses a joint filtration result from linear algebra. Lastly, a pointwise filtration approach, first considered by Corvaja, Levin, and Zannier, is used to give further improvements such that if q is greater than or equal to n 2 − n, then the curve is degenerate. This pointwise filtration may be constructed by using linear algebra on the power series locally representing the sections.
