Quasimaps to GIT fibre bundles and applications

open access: yesForum of Mathematics, Sigma, 2021
In [4], Brown proved that the I-function of a toric fibration lies on the overruled Lagrangian cone of its $g=0$ Gromov–Witten theory, introduced by Coates and Givental [8]. In this paper, we prove the theorem for partial flag-variety fibrations.

Equivariant Brill–Noether theory for elliptic operators and superrigidity of J-holomorphic maps

open access: yesForum of Mathematics, Sigma, 2023
The space of Fredholm operators of fixed index is stratified by submanifolds according to the dimension of the kernel. Geometric considerations often lead to questions about the intersections of concrete families of elliptic operators with these ...

Hodge integrals and tau-symmetric integrable hierarchies of Hamiltonian evolutionary PDEs [PDF]

open access: yes, 2014
For an arbitrary semisimple Frobenius manifold we construct Hodge integrable hierarchy of Hamiltonian partial differential equations. In the particular case of quantum cohomology the tau-function of a solution to the hierarchy generates the intersection ...

Wall-crossings in toric Gromov–Witten theory I: crepant examples [PDF]

open access: yes, 2006
Let X be a Gorenstein orbifold with projective coarse moduli space X and let Y be a crepant resolution of X . We state a conjecture relating the genus-zero Gromov‐ Witten invariants of X to those of Y , which differs in general from the Crepant ...

Standard versus reduced genus-one Gromov–Witten invariants [PDF]

open access: yes, 2007
We give an explicit formula for the difference between the standard and reduced genus-one Gromov‐Witten invariants. Combined with previous work on geometric properties of the latter, this paper makes it possible to compute the standard genus-one GW ...

The Gromov width of complex Grassmannians [PDF]

open access: yes, 2004
We show that the Gromov width of the Grassmannian of com- plex k-planes in C n is equal to one when the symplectic form is normalized so that it generates the integral cohomology in degree 2. We deduce the lower bound from more general results.

Lagrangians for the Gopakumar-Vafa conjecture [PDF]

open access: yes, 2002
This article explains how to construct immersed Lagrangian submanifolds in C 2 that are asymptotic at large distance from the origin to a given braid in the 3‐sphere.

Homological Lagrangian monodromy [PDF]

open access: yes, 2009
We show that the Hamiltonian Lagrangian monodromy group, in its homological version, is trivial for any weakly exact Lagrangian submanifold of a symplectic manifold.

The orientability problem in open Gromov–Witten theory [PDF]

open access: yes, 2012
We give an explicit formula for the holonomy of the orientation bundle of a family of real Cauchy‐Riemann operators. A special case of this formula resolves the orientability question for spaces of maps from Riemann surfaces with Lagrangian boundary ...

The Gromov invariant and the Donaldson-Smith standard surface count [PDF]

open access: yes, 2003
Simon Donaldson and Ivan Smith recently studied symplectic surfaces in symplectic 4{manifolds X by introducing an invariant DS associated to any Lefschetz bration on blowups of X which counts holomorphic sections of a relative Hilbert scheme that is ...
