Superheavy skeleta for non-normal crossings divisors

E Gathercole - arXiv preprint arXiv:2408.13187, 2024 - arxiv.org
Given an anticanonical divisor in a projective variety, one naturally obtains a monotone K\"
ahler manifold. In this paper, for divisors in a certain class (larger than normal crossings), we …

Symplectic topology and ideal-valued measures

A Dickstein, Y Ganor, L Polterovich, F Zapolsky - Selecta Mathematica, 2024 - Springer
We adapt Gromov's notion of ideal-valued measures to symplectic topology, and use it for
proving new results on symplectic rigidity and symplectic intersections. Furthermore, it …

On the spectral capacity of submanifolds

D Cant, J Zhang - arXiv preprint arXiv:2409.14142, 2024 - arxiv.org
The infimum of the spectral capacities of neighbourhoods of a nowhere coisotropic
submanifold is shown to be zero. In contrast, neighbourhoods of a closed Lagrangian …

Descent with algebraic structures for symplectic cohomology

U Varolgunes - arXiv preprint arXiv:2311.15934, 2023 - arxiv.org
We formulate and prove a chain level descent property of symplectic cohomology for
involutive covers by compact subsets that take into account the natural algebraic structures …

Spectral diameter of negatively monotone manifolds

Y Sun - arXiv preprint arXiv:2410.21416, 2024 - arxiv.org
For a closed negatively monotone symplectic manifold, we construct quasi-isometric
embeddings from the Euclidean spaces to its Hamiltonian diffeomorphism group, assuming …

-equivariant relative symplectic cohomology and relative symplectic capacities

J Ahn - arXiv preprint arXiv:2410.01977, 2024 - arxiv.org
In this paper, we construct an $ S^ 1$-equivariant version of the relative symplectic
cohomology developed by Varolgunes. As an application, we construct a relative version of …

Constraints on symplectic quasi-states

A Dickstein, F Zapolsky - arXiv preprint arXiv:2407.08014, 2024 - arxiv.org
We prove that given a closed connected symplectic manifold equipped with a Borel
probability measure, an arbitrarily large portion of the measure can be covered by a …

Heavy sets and index bounded relative symplectic cohomology

Y Sun - Journal of Fixed Point Theory and Applications, 2024 - Springer
We use relative symplectic cohomology to detect heavy sets, with the help of index bounded
contact forms. This establishes a relation between two notions SH-heaviness and …
