Stably unactivated neurons in ReLU neural networks

Natalie Brownlowe, Christopher R. Cornwell, Ethan Montes +3

The choice of architecture of a neural network influences which functions will be realizable by that neural network and, as a result, studying the expressiveness of a chosen archit…

Links and the Diaconis-Graham Inequality

Christopher Cornwell, Nathan McNew

In 1977 Diaconis and Graham proved two inequalities relating different measures of disarray in permutations, and asked for a characterization of those permutations for which equali…

Unknotted cycles

Christopher R. Cornwell, Nathan McNew

Noting that cycle diagrams of permutations visually resemble grid diagrams used to depict knots and links in topology, we consider the knot (or link) obtained from the cycle diagra…

Character varieties of knot complements and branched double-covers via the cord ring

Christopher R. Cornwell

We study the relationship between Ng's abelian cord ring and SL(2,C) characters of the two-fold branched cover . Augmentations, and their corresponding rank, play a central r…

Berge duals and universally tight contact structures

Christopher R. Cornwell

Dehn surgery on a knot determines a dual knot in the surgered manifold, the core of the filling torus. We consider duals of knots in that have a lens space surgery. Each dual…

Obstructions to Lagrangian concordance

Christopher R. Cornwell, Lenhard Ng, Steven Sivek

We investigate the question of the existence of a Lagrangian concordance between two Legendrian knots in . In particular, we give obstructions to a concordance from a…

Augmentation Rank of Satellites with Braid Pattern

Christopher R. Cornwell, David R. Hemminger

Given a knot in , a question raised by Cappell and Shaneson asks if the meridional rank of equals the bridge number of . Using augmentations in knot contact homolog…

KCH representations, augmentations, and -polynomials

Christopher Cornwell

We describe a correspondence between augmentations and certain representations of the knot group. The correspondence makes the 2-variable augmentation polynomial into a generalizat…

Bennequin type inequalities in lens spaces

Christopher R. Cornwell

We give criteria for an invariant of lens space links to bound the maximal self-linking number in certain tight contact lens spaces. As a corollary we extend the Franks-Williams-Mo…

A polynomial invariant for links in lens spaces

Christopher Cornwell

We prove the existence of a polynomial invariant that satisfies the HOMFLY skein relation for links in a lens space. In the process we also develop a skein theory of toroidal grid…
