Framed E2 structures in Floer theory

M Abouzaid, Y Groman, U Varolgunes - Advances in Mathematics, 2024 - Elsevier
We resolve the long-standing problem of constructing the action of the operad of framed
(stable) genus-0 curves on Hamiltonian Floer theory; this operad is equivalent to the framed …

Lectures on Lagrangian torus fibrations

JD Evans - arXiv preprint arXiv:2110.08643, 2021 - arxiv.org
This is a book aimed at graduate students and researchers in symplectic geometry, based
on a course I taught in 2019. The primary message is that the base of a Lagrangian torus …

Closed string mirrors of symplectic cluster manifolds

Y Groman, U Varolgunes - arXiv preprint arXiv:2211.07523, 2022 - arxiv.org
We compute the relative symplectic cohomology sheaf in degree $0 $ on the bases of nodal
Lagrangian torus fibrations on four dimensional symplectic cluster manifolds. We show that it …

Pinwheels as Lagrangian barriers

J Brendel, F Schlenk - Communications in Contemporary …, 2024 - World Scientific
The complex projective plane ℂ P 2 contains certain Lagrangian CW-complexes called
pinwheels, which have interesting rigidity properties related to solutions of the Markov …

Family Floer mirror space for local SYZ singularities

H Yuan - Forum of Mathematics, Sigma, 2024 - cambridge.org
We give a mathematically precise statement of the SYZ conjecture between mirror space
pairs and prove it for any toric Calabi-Yau manifold with the Gross Lagrangian fibration. To …

Local exotic tori

J Brendel - arXiv preprint arXiv:2310.11359, 2023 - arxiv.org
Let $(X,\omega) $ be a geometrically bounded symplectic manifold of dimension at least six.
We show that every open subset of $ X $ contains infinitely many Lagrangian tori which are …

Scattering diagrams in mirror symmetry

V Fantini - Bollettino dell'Unione Matematica Italiana, 2024 - Springer
Since the pioneering work of Kontsevich and Soibelman (in: The unity of mathematics,
Springer, Berlin, 2006), scattering diagrams have started playing an important role in mirror …

[PDF][PDF] Geometry & Topology

K SACKEL, A SONG, U VAROLGUNES… - Geometry & …, 2024 - scholar.archive.org
Consider R 2n with its standard symplectic structure! D Pdxi^ dyi. A prototypical question in
symplectic geometry is to ask whether one domain of R 2n symplectically embeds into …

The local Floer cohomology of indicator functions

Y Groman - arXiv preprint arXiv:2307.11659, 2023 - arxiv.org
For a compact set $ K $ with contact type boundary in a symplectic manifold $ M $ we
construct a spectral sequence from the local Floer homology of the Reeb orbits, as studied …

SYZ mirror symmetry for del Pezzo surfaces and affine structures

SC Lau, TJ Lee, YS Lin - Advances in Mathematics, 2024 - Elsevier
We prove that the Landau–Ginzburg superpotential of del Pezzo surfaces can be realized as
a limit of their hyperKähler rotation toward the large complex structure limit point. As a …
