A theorem of Delzant states that any symplectic manifold $(M,\om)$ of dimension $2n$, equipped with an effective Hamiltonian action of the standard $n$-torus $\T^n = \R^{n}/2\pi\Z^n$, is a smooth projective toric variety completely determined (as a Hamiltonian $\T^n$-space) by the image of the moment map $\phi:M\to\R^n$, a convex polytope $P=\phi(M)\subset\R^n$. In this paper we show, using symplectic (action-angle) coordinates on $P\times \T^n$, how all $\om$-compatible toric complex… 

Toric generalized Kähler structures

Given a compact symplectic toric manifold $(M,\omega, \mathbb{T})$, we identify a class $DGK_{\omega}^{\mathbb{T}}(M)$ of $\mathbb{T}$-invariant generalized K\"ahler structures for which a

Complex symplectomorphisms and pseudo-Kähler islands in the quantization of toric manifolds

Let $$P$$P be a Delzant polytope. We show that the quantization of the corresponding toric manifold $$X_{P}$$XP in toric Kähler polarizations and in the toric real polarization are related by

Bergman kernels and equilibrium measures for line bundles over projective manifolds

Let $L$ be a holomorphic line bundle over a compact complex projective Hermitian manifold $X.$ Any fixed smooth hermitian metric $\phi$ on $L$ induces a Hilbert space structure on the space of global

In this paper we study the smallest non-zero eigenvalue $$\lambda _1$$λ1 of the Laplacian on toric Kähler manifolds. We find an explicit upper bound for $$\lambda _1$$λ1 in terms of moment polytope

Construct $b$-symplectic toric manifolds from toric manifolds

In \cite{btoric}, Guillemin et al. proved a Delzant-type theorem which classifies $b$-symplectic toric manifolds. More generally, in \cite{torus} they proved a similar convexity result for general

Almost all Lagrangian torus orbits in $${\mathbb C}P^n$$CPn are not Hamiltonian volume minimizing

All principal orbits of the standard Hamiltonian $$T^n$$Tn-action on the complex projective space $${\mathbb C}P^n$$CPn are Lagrangian tori. In this article, we prove that most of them are not volume

Some remarks on the symplectic and Kähler geometry of toric varieties

Let M be a projective toric manifold. We prove two results concerning, respectively, Kähler–Einstein submanifolds of M and symplectic embeddings of the standard Euclidean ball in M. Both results use

Bernstein polynomials, Bergman kernels and toric Kähler varieties

It does not seem to have been observed previously that the classical Bernstein polynomials $B_N(f)(x)$ are closely related to the Bergman-Szego kernels $\Pi_N$ for the Fubini-Study metric on $\CP^1$:

Complete Ricci-flat K\"ahler metrics on the canonical bundles of toric Fano manifolds

We prove the existence of a complete Ricci-flat K\"ahler metric on the total space of the canonical line bundle $K_M$ of a toric Fano manifold $M$ as an application of the existence result of toric

In this paper, we analyze the relevance of the generalized Kronheimer construction for the gauge/gravity correspondence. We begin with the general structure of D3-brane solutions of type IIB
