Geometric invariant theory and flips
 Jour. AMS
, 1996
"... Ever since the invention of geometric invariant theory, it has been understood that the quotient it constructs is not entirely canonical, but depends on a choice: the choice of a linearization of the group action. However, the founders of the subject never made a systematic study of this dependence. ..."

GEOMETRIC INVARIANT THEORY
, 2012
"... Geometric Invariant Theory is the study of quotients in the context of algebraic geometry. Many objects we would wish to take a quotient of have some sort of geometric structure and Geometric Invariant Theory (GIT) allows us to construct quotients that preserve geometric structure. Quotients are nat ..."

Heights and geometric invariant theory
 Forum Mathematicum
"... Abstract. Let K be a number field, OK be its ring of integers. We introduce the notion of compactified representation of GLN(OK) and, we see how to associate to a hermitian vector bundle E over Spec(OK) and a compactified representation T, a hermitian tensor bundle ET. We can prove then that there e ..."

On small geometric invariants of
"... Abstract. A small geometric invariant is a nonnegative integer invariant associated with a 3manifold whose value is bounded above by the Heegaard genus of the manifold. Craggs has studied techniques to detect for a given 3manifold M 3, whether the double 2M = Bd(M ⋆ ×[−1, 1]) bounds a 4manifold N ..."

In this paper we will survey some recent developments in the last decade or so on variation of Geometric Invariant Theory and its applications to Birational Geometry such as the weak Factorization Theorems of nonsingular projective varieties and more generally projective varieties with finite quot ..."

SITE CHARACTERIZATIONS FOR GEOMETRIC INVARIANTS OF TOPOSES
"... Abstract. We discuss the problem of characterizing the property of a Grothendieck topos to satisfy a given ‘geometric ’ invariant as a property of its sites of definition, and indicate a set of general techniques for establishing such criteria. We then apply our methodologies to specific invariants, ..."
