Proposal of new topology information Face-list for manipulation planning of deformable string tying
SICE Journal of Control, Measurement, and System Integration, 2023 Our research group has been focusing on the automation of string tying-untying operations by a robot. In this paper, shape abstraction data of a string named Face-list and an operation planning method with Face-list are proposed.

Topology of strings: Median string is NP-complete
Theoretical Computer Science, 2000 Given a set of strings, the problem of finding a string that minimises its distance to the set is directly related with problems frequently encountered in areas involving pattern recognition or computational biology. Based on the Levenshtein (or edit) distance, different definitions of distances between a string and a set of strings can be adopted.

Hodge decomposition of string topology
Forum of Mathematics, Sigma, 2021 Let X be a simply connected closed oriented manifold of rationally elliptic homotopy type. We prove that the string topology bracket on the $S^1$-equivariant homology $ {\overline {\text {H}}}_\ast ^{S^1}({\mathcal {L}} X,{\mathbb {Q}}) $ of the free ...

Hypermultiplets and topological strings [PDF]
Journal of High Energy Physics, 2006 The c-map relates classical hypermultiplet moduli spaces in compactifications of type II strings on a Calabi-Yau threefold to vector multiplet moduli spaces via a further compactification on a circle. We give an off-shell description of the c-map in N=2 superspace.

Journal of High Energy Physics, 2020 We present two new classes of black string solutions in the context of mimetic gravity. The horizon topology of these solutions can be either a flat T 2 torus with topology S 1 × S 1, or a standard cylindrical model with topology R × S 1. The first class

Nuclear Physics B, 2020 Perturbative string amplitudes are correctly derived from the string geometry theory, which is one of the candidates of a non-perturbative formulation of string theory. In order to derive non-perturbative effects rather easily, we formulate topological string geometry theory.

Quantum entanglement of nontrivial spacetime topology
European Physical Journal C: Particles and Fields, 2020 We analyze the entanglement behaviors for two accelerating atoms interacting with a massless scalar field in the cosmic string spacetime. We calculate different correlation functions for different spacetime topologies. We find that entanglement behaviors
