Covering link calculus and iterated Bing doubles [PDF]
We give a new geometric obstruction to the iterated Bing double of a knot being a slice link: for n > 1 the (n+1)-st iterated Bing double of a knot is rationally slice if and only if the n-th iterated Bing double of the knot is rationally slice. The main

The Topology of Representational Geometry
Representational similarity analysis (RSA) is a powerful tool for abstracting and then comparing neural representations across brains, regions, models and modalities. However, typical RSA analyses compares pairs of representational dissimilarities to judge similarity of two neural systems, and we argue that such methods can not capture the shape of ...

Asymmetric L-space knots [PDF]
We construct the first examples of asymmetric L-space knots in S-3. More specifically, we exhibit a construction of hyperbolic knots in S-3 with both (i) a surgery that may be realized as a surgery on a strongly invertible link such that the result of ...

A note on T-folds and T 3 fibrations
We study stringy modifications of T 3-fibered manifolds, where the fiber undergoes a monodromy in the T-duality group. We determine the fibration data defining such T-folds from a geometric model, by using a map between the duality group and the group of

Synchronization of Caputo fractional neural networks with bounded time variable delays
One of the main problems connected with neural networks is synchronization. We examine a model of a neural network with time-varying delay and also the case when the connection weights (the influential strength of the jjth neuron to the iith neuron) are ...

Introduction to Periodic Geometry and Topology
This monograph introduces key concepts and problems in the new research area of Periodic Geometry and Topology for materials applications.Periodic structures such as solid crystalline materials or textiles were previously classified in discrete and coarse ways that depend on manual choices or are unstable under perturbations.

Differential Geometry of Identity Maps: A Survey [PDF]
An identity map idM:M→M is a bijective map from a manifold M onto itself which carries each point of M return to the same point. To study the differential geometry of an identity map idM:M→M, we usually assume that the domain M and the range M ...

Challenges and Opportunities in Machine Learning for Geometry [PDF]
Over the past few decades, the mathematical community has accumulated a significant amount of pure mathematical data, which has been analyzed through supervised, semi-supervised, and unsupervised machine learning techniques with remarkable results, e.g.,
