... (This data was obtained with the commands InvariantRing, PrimaryInvariants, and SecondaryInvariants in Magma.) One checks that R = R/f 1 R is an integral domain. Let S be the subring of R generated ... certain ad hoc tools, the central idea will always be to count fields by counting integral points on certain associated varieties, which are related to the invariant theory of t...

... al- gebraic subvarieties of X; a subvariety of X has a cycle class in the dual of a rational homology space of X and the duals of these cycle classes span a subspace of homology, which might be large. ... normalisation, the integral of an algebraic differential against a cycle class will be an algebraic number. The celebrated Hodge conjecture describes the s...

... stable subset of a minimal surface given as half of a normal tubular neighborhood (in the surface) of a strictly convex curve. For instance, a curve lying in the boundary of an intrinsic ball is strictly ... large since η ε j ∪ γ ε j ,3 separate Σ ε j ,1 and σ 2 . The next lemma bounds the area of a minimal surface with two sides and an interior boundary in...

... facts about minimal surfaces in a slab will be used: • Stable surfaces in a slab must be graphical away from their boundary (see Lemma I.0.9 below). • The maximum principle, and catenoid foliations ... understanding such surfaces is to un- derstand the local structure in a ball and in particular the structure of an embedded minimal disk in a ball in R 3 (with th...
