Geometric stability via information theory
The Loomis-Whitney inequality, and the more general Uniform Cover inequality, bound the volume of a body in terms of a product of the volumes of lowerdimensional projections of the body. In this paper, we prove stability versions of these inequalities, showing that when they are close to being tight, the body in question is close in symmetric difference to a box. Our results are best possible u...
متن کاملElements of Geometric Stability Theory
1 Completeness and quantifier elimination for some classical theories We first work out a basic example, with a proof that demonstrates geometro-algebraic, as opposed to syntactical, methods in model theory. We denote ACF p the theory of algebraically closed fields of characteristic p. Theorem 1.1 ACF p is complete and allows quantifier elimination in the language (+, ·, 0, 1) First we prove Le...
متن کاملIntroduction to Geometric Stability Theory
I will use David Marker’s book [Mar] as the basic reference for the talks, partly because it’s likely to be the easiest one to find. Other presentations are available: the books by Hodges [Hod], Poizat [PoE] are also excellent (and Poizat in French [PoF] is even better). The classic text on model theory is by Chang and Keisler [ChK]. To go deeper into geometric stability theory you should look ...
متن کاملAn Introduction to Geometric Stability Theory
In this paper, we will introduce some of the most basic concepts in geometric stability theory, and attempt to state a dichotomy theorem proved by Buechler. We will state and prove one of the requisite lemmas, though we will not provide a proof of the theorem itself.
متن کاملGeometric Invariant Theory via Cox Rings
We consider actions of reductive groups on a varieties with finitely generated Cox ring, e.g., the classical case of a diagonal action on a product of projective spaces. Given such an action, we construct via combinatorial data in the Cox ring all maximal open subsets such that the quotient is quasiprojective or embeddable into a toric variety. As applications, we obtain an explicit description...
