Projectively Normal Curves Defined by Quadrics
We study the projectively normal embeddings of small degree of smooth curves of genus g such that the ideal of the embedded curves is generated by quadrics.
متن کاملProjectively Bounded Fréchet Measures
A scalar valued set function on a Cartesian product of σ-algebras is a Fréchet measure if it is a scalar measure independently in each coordinate. A basic question is considered: is it possible to construct products of Fréchet measures that are analogous to product measures in the classical theory? A Fréchet measure is said to be projectively bounded if it satisfies a Grothendieck type inequali...
متن کاملNormal Surfaces
We define a 2-normal surface to be one which intersects every 3-simplex of a triangulated 3-manifold in normal triangles and quadrilaterals, with one or two exceptions. The possible exceptions are a pair of octagons, a pair of unknotted tubes, an octagon and a tube, or a 12-gon. In this paper we use the theory of critical surfaces developed in [Baca] to prove the existence of topologically inte...
متن کاملFrom Normal Surfaces to Normal Curves to Geodesics on Surfaces
Motivated by the topological theory of normal surface we give in this paper a complete study of the relations between geodesic curves and normal curves embedded in a triangulated Riemannian surface. Normal surface theory is a topological piecewise linear (p` for short) counterpart of the differential geometric theory of minimal surfaces. This theory studies the ways surfaces intersect with a gi...
متن کاملExotic structures and adjunction inequality
Theorem 1.1. ([E]) Let X = B ∪ (1-handles) ∪ (2-handles) be four-dimensional handlebody with one 0-handle and no 3or 4-handles. Then • The standard symplectic structure on B can be extended over 1-handles so that manifold X1 = B 4 ∪ (1-handles) is a compact Stein domain. • If each 2-handle is attached to ∂X1 along a Legendrian knot with framing one less then Thurston-Bennequin framing of this k...
