Orbifold string topology [PDF]

Geometry & Topology, 2008
In this paper we study the string topology ( la Chas-Sullivan) of an orbifold. We define the string homology ring product at the level of the free loop space of the classifying space of an orbifold. We study its properties (introducing an operad to do so) and do some explicit calculations.

Topological string geometry

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.

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.

Topological Strings on Non-commutative Resolutions [PDF]

Communications in Mathematical Physics
AbstractIn this paper we propose a definition of torsion refined Gopakumar–Vafa (GV) invariants for Calabi–Yau threefolds with terminal nodal singularities that do not admit Kähler crepant resolutions. Physically, the refinement takes into account the charge of five-dimensional BPS states under a discrete gauge symmetry in M-theory.

Topological strings and Wilson loops

Journal of High Energy Physics, 2022
We propose the refined topological string correspondence to the expectation values of half-BPS Wilson loop operators in 5d N $$ \mathcal{N} $$ = 1 gauge theory partition function on the Omega-deformed background ℝ ϵ 1 , 2 4 $$ {\mathbb{R}}_{\upepsilon_{1,

Stability of topological solitons, and black string to bubble transition

Journal of High Energy Physics, 2022
We study the existence of smooth topological solitons and black strings as locally-stable saddles of the Euclidean gravitational action of five dimensional Einstein-Maxwell theory.

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.

Topological string entanglement [PDF]

Journal of High Energy Physics, 2019
Abstract We investigate how topological entanglement of Chern-Simons theory is captured in a string theoretic realization. Our explorations are motivated by a desire to understand how quantum entanglement of low energy open string degrees of freedom is encoded in string theory (beyond the oft discussed classical gravity limit ...
