A log PSS morphism with applications to Lagrangian embeddings

چکیده

Let $M$ be a smooth projective variety and $\mathbf{D}$ an ample normal crossings divisor. From topological data associated to the pair $(M, \mathbf{D})$, we construct, under assumptions on Gromov-Witten invariants, series of distinguished classes in symplectic cohomology complement $X = M \backslash \mathbf{D}$. Under further "topological" pair, these can organized into Log(arithmic) PSS morphism, from vector space which term logarithmic \mathbf{D})$ cohomology. Turning applications, show that methods some knowledge invariants used produce dilations quasi-dilations (in sense Seidel-Solomon [SS]) examples such as conic bundles. In turn, existence elements imposes strong restrictions exact Lagrangian embeddings, especially dimension 3. For instance, prove any complex 3-dimensional bundle over $(\mathbb{C}^*)^2$ must diffeomorphic $T^3$ or connect sum $\#^n S^1 \times S^2$.

A Lagrangian Piunikhin-salamon-schwarz Morphism

In this article we explore to what extend the techniques of Piunikhin, Salamon and Schwarz in [PSS96] can be carried over to Lagrangian Floer homology. In [PSS96] the authors establish an isomorphism between Hamiltonian Floer homology and singular homology of the underlying symplectic manifold. In general, Lagrangian Floer homology is not isomorphic to the singular homology of the Lagrangian su...

Haldane limits via Lagrangian embeddings

In the present paper we revisit the so-called Haldane limit, i.e. a particular continuum limit, which leads from a spin chain to a sigma model. We use the coherent state formulation of the path integral to reduce the problem to a semiclassical one, which leads us to the observation that the Haldane limit is closely related to a Lagrangian embedding into the classical phase space of the spin cha...

Novikov-symplectic Cohomology and Exact Lagrangian Embeddings

We prove that if N is a closed simply connected manifold and j : L →֒ T ∗N is an exact Lagrangian embedding, then H2(N) → H2(L) is injective and the image of π2(L) → π2(N) has finite index. Viterbo proved that there is a transfer map on free loopspaces H∗(L0N) → H∗(L0L) which commutes under the inclusion of constant loops with the ordinary transfer map H∗(N) → H∗(L). This commutative diagram sti...

Mean Curvature Flow and Lagrangian Embeddings

In this note we provide examples of compact embedded lagrangians in Cn for any n ≥ 2 that under mean curvature flow develop singularities in finite time. When n is odd the lagrangians can be taken to be orientable. By gluing these lagrangians onto a special lagrangian embedding L we provide examples of compact embedded lagrangians in a Calabi-Yau manifold that under mean curvature flow develop ...

A Lagrangian Piunikhin-salamon-schwarz Morphism and Two Comparison Homomorphisms in Floer Homology

A. This article address two issues. First, we explore to what extend the techniques of Piunikhin, Salamon and Schwarz in [PSS96] can be carried over to Lagrangian Floer homology. In [PSS96] an isomorphism between Hamiltonian Floer homology and singular homology is established. In contrast, Lagrangian Floer homology is not isomorphic to the singular homology of the Lagrangian submanifold,...
