Let C be the topological knot concordance group of knots $S^{1} \subset S^{3}$ under connected sum modulo slice knots. Cochran, Orr and Teichner defined a filtration: \[C \supset F_{(0)} \supset F_{(0.5)} \supset F_{(1)} ...

In this article, we shall show that the metrics defined by Feng and Mao, and Du are equivalent. We also provide some examples for one of the metrics.
• (Indiana University Department of Mathematics, 2010)
In natural logic, the goal is to create a system of logic that is as sim- ilar to natural language as possible. In order to build a natural logic, simple sentence forms are considered, slowly incorporating more ...

We introduce systems of objects and operators in linear monoidal categories called $\hat{\Psi}$-systems. A $\hat{\Psi}$-system satisfying several additional assumptions gives rise to a topological invariant of triples (a ...

Given a CAT(0) group G acting geometrically on a proper CAT(0) space, we attempt to demonstrate that any torsion subgroup of G has nite cardinality.
