The (n)-Solvable Filtration of the Link Concordance Group and Milnor's mu-Invariaants
We establish several new results about the ( n )-solvable filtration, [Special characters omitted.] , of the string link concordance group [Special characters omitted.] . We first establish a relationship between ( n ...
Minimizing the mass of the codimension-two skeleton of a convex, volume-one polyhedral region
In this paper we establish the existence and partial regularity of a (d-2)-dimensional edge-length minimizing polyhedron in [Special characters omitted.] . The minimizer is a generalized convex polytope of volume one which ...
Rational points on del Pezzo surfaces of degree 1 and 2
One of the fundamental problems in Algebraic Geometry is to study solutions to certain systems of polynomial equations in several variables, or in other words, find rational points on a given variety which is defined by ...
