Fruit flies and moduli: interactions between biology and mathematics [PDF]

open access: yes, 2015
Possibilities for using geometry and topology to analyze statistical problems in biology raise a host of novel questions in geometry, probability, algebra, and combinatorics that demonstrate the power of biology to influence the future of pure ...

Deficits of the “Good” Eye in Amblyopia: Processing Geometric Properties

open access: yesInvestigative Ophthalmology and Visual Science
Purpose Although fellow eyes of amblyopia are typically considered normal, recent studies have revealed impairments in certain aspects of vision. However, it remains unclear at which level of object processing these impairments occur.

Geodesic knots in cusped hyperbolic 3-manifolds

open access: yes, 2009
We consider the existence of simple closed geodesics or "geodesic knots" in finite volume orientable hyperbolic 3-manifolds. Previous results show that at least one geodesic knot always exists [Bull. London Math. Soc.

Topological Hochschild cohomology and generalized Morita equivalence [PDF]

open access: yes, 2004
We explore two constructions in homotopy category with algebraic precursors in the theory of noncommutative rings and homological algebra, namely the Hochschild cohomology of ring spectra and Morita theory.

An outlined tour of geometry and topology as perceived through physics and mathematics emphasizing geometrization, elliptization, uniformization, and projectivization for Thruston's 8-geometries covering Riemann over Teichmuller spaces

open access: yes, 2022
<p>Equivalence, duality, and invariance are the pin-points of unification in modern theoretical physics that got the twist of topologies when going beyond the notions of differential and conformal domains to geometries to the symplectic norm of topologies with the pillars being the algebraic geometry taking the counting of specified states ...

Group approximation in Cayley topology and coarse geometry, Part III: Geometric property (T) [PDF]

open access: yes, 2014
In this series of papers, we study correspondence between the following: (1) large scale structure of the metric space bigsqcup_m {Cay(G(m))} consisting of Cayley graphs of finite groups with k generators; (2) structure of groups which appear in the ...

Renormalization in one-dimensional dynamics

open access: yesRussian Mathematical Surveys, 2023
The study of the dynamical and topological properties of interval exchange transformations and their natural generalizations is an important problem, which lies at the intersection of several branches of mathematics, including dynamical systems, low ...

Intrinsic linking and knotting of graphs in arbitrary 3-manifolds [PDF]

open access: yes, 2005
We prove that a graph is intrinsically linked in an arbitrary 3-manifold M if and only if it is intrinsically linked in S^3. Also, assuming the Poincare Conjecture, we prove that a graph is intrinsically knotted in M if and only if it is intrinsically ...

The concordance genus of knots

open access: yes, 2004
In knot concordance three genera arise naturally, g(K), g_4(K), and g_c(K): these are the classical genus, the 4-ball genus, and the concordance genus, defined to be the minimum genus among all knots concordant to K. Clearly 0

Nullification functors and the homotopy type of the classifying space for proper bundles [PDF]

open access: yes, 2005
Let G be a discrete group for which the classifying space for proper G-actions is finite-dimensional. We find a space W such that for any such G, the classifying space PBG for proper G-bundles has the homotopy type of the W-nullification of BG.
