Topology and Geometry of Biopolymers
1996This paper is concerned with some simple lattice models of the entanglement complexity of polymers in dilute solution, with special reference to biopolymers such as DNA. We review a number of rigorous results about the asymptotic behaviour of the knot probabihty, the entanglement complexity and the writhe of a lattice polygon (as a model of a ring ...

A Topological Approach to Geometry
The American Mathematical Monthly, 1966The purpose of this paper is to summarize a method by which at least certain topological spaces can be characterized up to homeomorphism class. The method employs the notion of a geometry defined on a set by means of distinguished subsets called k-flats which are generalizations of k-dimensional subspaces.

We provide here some concrete examples in which it is possible to compute the Seiberg-Witten invariants for some classes of four-manifolds.

Topology and Geometry for Physicists [PDF]
Physics Bulletin, 1984 Charles Nash and Siddhartha Sen 1983 London: Academic x + 311 pp price £25 ISBN 0 12 514080 0 One of the remarkable developments of the last decade is the penetration of topological concepts into theoretical physics. Homotopy groups and fibre bundles have become everyday working tools.

The earlier chapter of this self-contained text provide a route from first principles through standard linear and quadratic algebra to geometric algebra, with Clifford's geometric algebras taking pride of place. In parallel with this is an account, also from first principles, of the elementary theory of topological spaces and of continuous and ...

Molecular Topology and Geometry
1977Three main topics will be considered in this chapter, each of then corresponding to one of three major computing steps preceeding the calculation and minimisation of molecular potential energy and, therefore, all other calculations under the programming system: (a) analysis of molecular topology, (b) generation of lists of ...

Skyrmions, topology and geometry
2014Το θέμα της διατριβής είναι η μελέτη του μοντέλου του Skyrme σε διάφοραπλαίσια: από τη γενική θεωρία της σχετικότητας ως την πυρηνική φυσική καιφυσική συμπυκνωμένης ύλης. Δεδομένου ότι το μοντέλο δεν είναιολοκληρώσιμο αλλά τοπολογικό, λόγω της ύπαρξης του ενεργειακούφράγματος Bogomol'nyi, η μελέτη του έχει βασιστεί σε τοπολογικές καιγεωμετρικές ...

Attempts to understand the phenomenon of the robustness of the values of the Hall conductivity in quantum Hall systems led to the idea of characterizing the ground state of many electron systems using topological invariants. The discovery of the so called geometric phase in quantum systems led to the exploration of the quantum geometry of many electron
