String topology in three flavors [PDF]
EMS Surveys in Mathematical Sciences, 2023 We describe two major string topology operations, the Chas–Sullivan product and the Goresky–Hingston coproduct, from geometric and algebraic perspectives. The geometric construction uses Thom–Pontrjagin intersection theory while the algebraic construction is phrased in terms of Hochschild homology.

Rational string topology [PDF]
Journal of the European Mathematical Society, 2007 We use the computational power of rational homotopy theory to provide an explicit cochain model for the loop product and the string bracket of a 1-connected closed manifold M . We prove that the loop homology of

Spectral sequences in string topology [PDF]
Algebraic & Geometric Topology, 2011 In this paper, we investigate the behaviour of the Serre spectral sequence with respect to the algebraic structures of string topology in generalized homology theories, specificially with the Chas-Sullivan product and the corresponding coproduct and module structures.

Some computations in string topology [PDF]
, 2023 In this paper, we discuss Hochschild chain models for some of the string topology operations. We use these models to simplify the proofs and computations of some of the results in string topology. Along the way we also make some new observations.

Internal and String Stability Analysis for Vehicle Platooning under the MPF Topology under Communication Limitations [PDF]
, 2023 This thesis focuses on the analysis of internal stability and string stability of vehicle platoons under the multiple-predecessor following (MPF) topology, a configuration intended to lower the minimum employable time headway and increase road throughput.

Topological strings on elliptic fibrations [PDF]
Communications in Number Theory and Physics, 2014 We study topological string theory on elliptically fibered Calabi-Yau threefolds using mirror symmetry. We compute higher genus topological string amplitudes and express these in terms of polynomials of functions constructed from the special geometry of the moduli space. The polynomials are fixed by the holomorphic anomaly equations supplemented by the

Adaptive radial basis function sliding mode control for platoons under DoS attacks
IET Intelligent Transport Systems, 2023 This paper proposes an adaptive sliding mode control based on an auxiliary distance sensor for nonlinear platoons over vehicular ad‐hoc networks under Denial‐of‐Services (DoS) attacks and external disturbances.

S-duality and Topological Strings [PDF]
Journal of High Energy Physics, 2004 In this paper we show how S-duality of type IIB superstrings leads to an S-duality relating A and B model topological strings on the same Calabi-Yau as had been conjectured recently: D-instantons of the B-model correspond to A-model perturbative amplitudes and D-instantons of the A-model capture perturbative B-model amplitudes.
