The homology of a free loop space [PDF]
Denote by \(X^{S^ 1}\) the space of all continuous maps from the circle into a simply connected finite CW complex X. Theorem: Let \({\mathbb{K}}\) be a field and suppose that either char \({\mathbb{K}}>\dim X\) or that X is \({\mathbb{K}}\)-formal. Then the Betti numbers \(b_ q=\dim H_ q(X^{S^ 1};{\mathbb{K}})\) are uniformly bounded above if and only ...

Termination Analysis of Single Path Loop Programs Based on Iterative Trajectory Division [PDF]
The ranking function has been extensively studied as an important method of program termination analysis.In this paper,we focus on the termination of single-path loops.Firstly,the concept of two-way iterative loops is proposed,and the single-path loops ...

Braided injections and double loop spaces [PDF]
We consider a framework for representing double loop spaces (and more generally E-2 spaces) as commutative monoids. There are analogous commutative rectifications of braided monoidal structures and we use this framework to define iterated double ...

Bio-Cyber-Physical ‘Planetoids’ for Repopulating Residual Spaces
Minimal interventions that provide various microclimates can stimulate both biodiversity and social accessibility of leftover spaces. New habitats are often developed for different animal and plant species based on studies of the microclimates typical ...

Survey on real forms of the complex A2(2)-Toda equation and surface theory
The classical result of describing harmonic maps from surfaces into symmetric spaces of reductive Lie groups [9] states that the Maurer-Cartan form with an additional parameter, the so-called loop parameter, is integrable for all values of the loop ...

Suboptimal controller design of global active noise control system for various acoustic environments
Conventional active noise control (ANC) systems in enclosed spaces are not easy to implement experimentally because they require a large number of microphones to measure sound pressure in global areas.

On the geometry of free loop spaces
We verify the following three basic results on the free loop space LM. (1) We show that the set of all points, where the fundamental form on LM is nondegenerate, is an open subset.

Periodic billiard trajectories and Morse theory on loop spaces [PDF]
We study periodic billiard trajectories on a compact Riemannian manifold with boundary, by applying Morse theory to Lagrangian action functionals on the loop space of the manifold.

On the Space-of-Loops Isomorphism [PDF]
For X an arc-wise connected topological space with base point x0, let OX be the space of loops on X; that is, OX is the subset of the function space XI consisting of all paths X: I-*>X such that X(O) =X(1) =x0, where I is the unit interval. Let I Q| X be the geometric realization of the singular complex of QX; |Q|I X is a CW-complex [5].

Spectra of sigma models on semi-symmetric spaces
Sigma models on semi-symmetric spaces provide the central building block for string theories on AdS backgrounds. Under certain conditions on the global supersymmetry group they can be made one-loop conformal by adding an appropriate fermionic Wess–Zumino
