Higher String Topology Operations

چکیده
In [1] Chas and Sullivan have defined an intersection-type product on the homology of the free loop space LM of an oriented manifold M. In this paper we show how to extend this construction to a topological conformal field theory of degree d. In particular, we get operations on H∗LM which are parameterized by the homology of the moduli space of open-closed Riemann surfaces.

A new virtual leader-following consensus protocol to internal and string stability analysis of longitudinal platoon of vehicles with generic network topology under communication and parasitic delays
In this paper, a new virtual leader following consensus protocol is introduced to perform the internal and string stability analysis of longitudinal platoon of vehicles under generic network topology. In all previous studies on multi-agent systems with generic network topology, the control parameters are strictly dependent on eigenvalues of network matrices (adjacency or Laplacian). Since some ...
متن کاملMorse theory, graphs, and string topology
In these lecture notes we discuss a body of work in which Morse theory is used to construct various homology and cohomology operations. In the classical setting of algebraic topology this is done by constructing a moduli space of graph flows, using homotopy theoretic methods to construct a virtual fundamental class, and evaluating cohomology classes on this fundamental class. By using similar c...
متن کاملString Operations for Manifolds Using Radial Slit Configurations
These are notes for a lecture at the University of Lille. These discuss a method to construct higher string operations for manifolds. This method is based on Godin’s construction, but replaces the geometric realistion of a category of decorated ribbon graphs by Bödigheimer’s radial slit configurations model for the moduli space of Riemann surfaces with boundary. This significantly simplifies th...
متن کاملThird-order Decentralized Safe Consensus Protocol for Inter-connected Heterogeneous Vehicular Platoons
In this paper, the stability analysis and control design of heterogeneous traffic flow is considered. It is assumed that the traffic flow consists of infinite number of cooperative non-identical vehicular platoons. Two different networks are investigated in stability analysis of heterogeneous traffic flow: 1) inter-platoon network which deals with the communication topology of lead vehicles and...
متن کاملDe Rham model for string topology
0. Introduction. Let M be a simply connected closed oriented n-dimensional manifold, and LM := Map C ∞ (S 1 , M) the associated free loop space. String topology of Chas and Sul-livan [CS] deals with an ample family of algebraic operations on the ordinary and equivariant homologies of LM , the most important being a graded commutative associative product,
متن کاملThe Space of String Diagrams
where M is a closed, compact, oriented Riemannian manifold, LM is the space of continuous maps from the circle into M–the free loop space of M–and C∗(LM) is the complex of singular chains on LM . Inspired by an idea in [6], chain-level string topology operations were constructed in [5] using a subspace of our space of string diagrams. This subspace • has a different homotopy type from the space...
