A Semi-Smooth Kodaira Vanishing Theorem and Demi-Normal Cyclic Covering Lemma

Jeremy Berquist

The classical Kodaira Vanishing Theorem states that Hi(X, ωX \otimes L) = 0 for i > 0, where X is a smooth projective variety over C and L is an ample line bundle on X. We prove an…

Demi-Normal Surface Singularities

Jeremy Berquist

We prove semi-rationalification and semi-log-canonicalization for Gorenstein demi-normal surfaces. That is, given a Gorenstein demi-normal surface X with semi-rational (respectivel…

Singularities on Demi-Normal Varieties

Jeremy Berquist

The birational classification of varieties inevitably leads to the study of singularities. The types of singularities that occur in this context have been studied by Mori, Kollár,…

Rational and Semi-Rational Singularities

Jeremy Berquist

It is a conjecture of Kollár that a variety X with rational singularities in some open subvariety U has a rationalification; that is, a proper, birational morphism $f: Y \right…
