M2-brane partition functions and HD supergravity from equivariant volumes
Luca Cassia, Kiril Hristov
We use the results of our companion paper arXiv:2502.20444, which explores the equivariant generalization of the constant-map contribution in topological string theory on toric Cal…
Constant maps in equivariant topological strings and geometric modeling of fluxes
Luca Cassia, Kiril Hristov
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 t…
Symplectic cuts and open/closed strings II
Luca Cassia, Pietro Longhi, Maxim Zabzine
In arXiv:2306.07329 we established a connection between symplectic cuts of Calabi-Yau threefolds and open topological strings, and used this to introduce an equivariant deformation…
Symplectic cuts and open/closed strings I
Luca Cassia, Pietro Longhi, Maxim Zabzine
This paper introduces a concrete relation between genus zero closed Gromov-Witten invariants of Calabi-Yau threefolds and genus zero open Gromov-Witten invariants of a Lagrangian $…
