Corank

In mathematics, corank is complementary to the concept of the rank of a mathematical object, and may refer to the dimension of the left nullspace of a matrix, the dimension of the cokernel of a linear transformation of a vector space, or the number of elements of a matroid minus its rank. (Wikipedia).

Shin-ichi Tanigawa: Sufficient Conditions for Unique Graph Realizations

A graph is called globally rigid (or uniquely realizable) if for any generic embedding of it in d-dimensional Euclidean space there is no other embedding with the same edge-lengths (up to congruence). The global rigidity of graphs is one of the central topics in rigidity theory, and two ma

Comparing the corank of fine Selmer group and Selmer group of elliptic curves by Sudhanshu Shekhar

12 December 2016 to 22 December 2016 VENUE : Madhava Lecture Hall, ICTS Bangalore The Birch and Swinnerton-Dyer conjecture is a striking example of conjectures in number theory, specifically in arithmetic geometry, that has abundant numerical evidence but not a complete general solution.

Emanuel Milman: Functional Inequalities on sub-Riemannian manifolds via QCD

We are interested in obtaining Poincar ́e and log-Sobolev inequalities on domains in sub-Riemannian manifolds (equipped with their natural sub-Riemannian metric and volume measure). It is well-known that strictly sub-Riemannian manifolds do not satisfy any type of Curvature-Dimension condi
