Toeplitz Operators, K\"ahler Manifolds, and Line Bundles [PDF]

open access: yes, 2007
This is a survey paper. We discuss Toeplitz operators in K\"ahler geometry, with applications to geometric quantization, and review some recent developments.Comment: This is a contribution to the Proceedings of the 2007 Midwest Geometry Conference in ...

Fukaya Categories as Categorical Morse Homology [PDF]

open access: yes, 2014
The Fukaya category of a Weinstein manifold is an intricate symplectic invariant of high interest in mirror symmetry and geometric representation theory. This paper informally sketches how, in analogy with Morse homology, the Fukaya category might result

Poisson Manifolds, Lie Algebroids, Modular Classes: a Survey [PDF]

open access: yes, 2008
After a brief summary of the main properties of Poisson manifolds and Lie algebroids in general, we survey recent work on the modular classes of Poisson and twisted Poisson manifolds, of Lie algebroids with a Poisson or twisted Poisson structure, and of ...

Heisenberg model in pseudo-Euclidean spaces [PDF]

open access: yes, 2014
We construct analogues of the classical Heisenberg spin chain model (or the discrete Neumann system) on pseudo-spheres and light-like cones in the pseudo-Euclidean spaces and show their complete Hamiltonian integrability.

Fiberwise volume growth via Lagrangian intersections [PDF]

open access: yes, 2005
We consider Hamiltonian diffeomorphisms $\phi$ of the unit cotangent bundle over a closed Riemannian manifold $(M,g)$ which extend to Hamiltonian diffeomorphisms of $T^*M$ equal to the time-1-map of the geodesic flow for $|p| \ge 1$.

Groupoids, Frobenius algebras and Poisson sigma models [PDF]

open access: yes, 2013
In this paper we discuss some connections between groupoids and Frobenius algebras specialized in the case of Poisson sigma models with boundary. We prove a correspondence between groupoids in the category Set and relative Frobenius algebras in the ...

Enumerative invariants of stongly semipositive real symplectic six-manifolds [PDF]

open access: yes, 2007
Following the approach of Gromov and Witten, we define invariants under deformation of stongly semipositive real symplectic six-manifolds. These invariants provide lower bounds in real enumerative geometry, namely for the number of real rational $J ...

Homological mirror symmetry is T-duality for $\mathbb P^n$

open access: yes, 2008
In this paper, we apply the idea of T-duality to projective spaces. From a connection on a line bundle on $\mathbb P^n$, a Lagrangian in the mirror Landau-Ginzburg model is constructed.

Exact Lagrangian submanifolds in simply-connected cotangent bundles

open access: yes, 2007
We consider exact Lagrangian submanifolds in cotangent bundles. Under certain additional restrictions (triviality of the fundamental group of the cotangent bundle, and of the Maslov class and second Stiefel-Whitney class of the Lagrangian submanifold) we

Poisson Geometry in Constrained Systems

open access: yes, 2002
Constrained Hamiltonian systems fall into the realm of presymplectic geometry. We show, however, that also Poisson geometry is of use in this context.
