Lipschitz homotopies of mappings from 3-sphere to 2-sphere
This work focuses on important step in quantitative topology: given homotopic mappings from S^m to S^n of Lipschitz constant L, build the (asymptotically) simplest homotopy between them (meaning having the least Lipschitz constant). The present paper resolves this problem for the first case where …

Virtual strings for closed curves with multiple components and filamentations for virtual links
… description of closed curves in the 2-sphere (and therefore 2-dimensional Euclidean space) in terms of Gauss paragraphs and word-wise partitions of their alphabet sets. In addition, we prove that the unordered triple consisting of the Gauss paragraph, the word-wise partition, and a …

The Bing sphere characterization and applications of brick partitioning
… Characterization of higher dimensional spheres is still incomplete.</p> <p>The characterization of the 2-sphere as a Peano space containing a simple closed curve, which is separated by every simple closed curve but by no arc of a simple closed curve was accomplished in 1930 by Leo Zippin …

Analytical and Computational Studies of Lennard-Jones Thin Rods
… have been reported for simple geometries such as spheres and planes, compact analytical forms for rod-like particles have remained elusive. This dissertation presents a comprehensive theoretical framework and computational implementation for studying LJ interactions involving thin rod-like …
