Vacuum Interaction of Topological Strings at Short Distances

Physics, 2023
The paper provides an extended overview of recent results obtained by the authors in the process of studying the vacuum interaction of topological cosmic strings at short distances, taking into account their transverse size a and the mass m of the ...

Intrinsic non-perturbative topological strings

Advances in Theoretical and Mathematical Physics, 2021
We study difference equations which are obtained from the asymptotic expansion of topological string theory on the deformed and the resolved conifold geometries as well as for topological string theory on arbitrary families of Calabi-Yau manifolds near ...

STRING TOPOLOGICAL ROBOTICS

JP Journal of Geometry and Topology, 2016
If one regards a topological space \(X\) as the configuration space of a given mechanical system, a motion planning algorithm takes pairs of configurations \((A,B)\in X\times X\) as an input and produces as an output a continuous path in \(X\) which starts at \(A\) and ends at \(B.\) In other words, a motion planning algorithm is precisely a section ...

Constant maps in equivariant topological strings and geometric modeling of fluxes

Journal of Physics A: Mathematical and Theoretical
We study the equivariant generalization of topological strings on toric manifolds, focusing in particular on defining the contributions of constant maps in the genus expansion of the partition function.

Topological strings, quiver varieties, and Rogers–Ramanujan identities

, 2017
Motivated by some recent works on BPS invariants of open strings/knot invariants, we guess there may be a general correspondence between the Ooguri–Vafa invariants of toric Calabi–Yau 3-folds and cohomologies of Nakajima quiver varieties.

TOPOLOGICAL STRINGS

2005
AbstractType-A and type-B topological sigma models are two topological field theories in two dimensions. Although they contain a lot of information in genus 0, they turn out to be trivial for g > 1. This is essentially due to the fact that, in order to define these theories, it is necessary to consider a fixed metric in the Riemann surface.

BOSONIC STRING WITH TOPOLOGICAL TERM

Modern Physics Letters A, 1991
It is shown that in D = 3 space-time dimensions there exist a topological term for the bosonic strings. The corresponding constraints satisfy the same Virasoro algebra as the ordinary bosonic strings. These results are generalized for an arbitrary dimensional space-time if we have SO (1, 2) ⊗ O (D − 3) or SO (3) ⊗ O (1, D − 4) symmetry instead of SO ...
