Integral-integral affine geometry, geometric quantization, and Riemann-Roch

Mark Hamilton, Yael Karshon, Takahiko Yoshida

We give a simple proof that, for a pre-quantized compact symplectic manifold with a Lagrangian torus fibration, its Riemann-Roch number coincides with its number of Bohr-Sommerfeld…

Adiabatic Limit, Theta Function, and Geometric Quantization

Takahiko Yoshida

Let be a non-singular Lagrangian torus fibration on a complete base with prequantum line bundle . Compactness on is no…

The equivariant local index of the reduced space in the symplectic cutting

Takahiko Yoshida

We compute the equivariant local index for the reduced space in a symplectic cut space, provided that the reduced space is compact.

Geodesic flows on spheres and the local Riemann-Roch numbers

Hajime Fujita, Mikio Furuta, Takahiko Yoshida

We calculate the local Riemann-Roch numbers of the zero sections of and , where the local Riemann-Roch numbers are defined by using the -bundle structure o…

Torus fibrations and localization of index III

Hajime Fujita, Mikio Furuta, Takahiko Yoshida

This paper is the third of the series concerning the localization of the index of Dirac-type operators. In our previous papers we gave a formulation of index of Dirac-type operator…

Torus fibrations and localization of index II

Hajime Fujita, Mikio Furuta, Takahiko Yoshida

We give a framework of localization for the index of a Dirac-type operator on an open manifold. Suppose the open manifold has a compact subset whose complement is covered by a fami…

Torus fibrations and localization of index I

Hajime Fujita, Mikio Furuta, Takahiko Yoshida

We define a local Riemann-Roch number for an open symplectic manifold when a complete integrable system without Bohr-Sommerfeld fiber is provided on its end. In particular when a s…

On Liftings of Local Torus Actions to Fiber Bundles

Takahiko Yoshida

In this note we define a lifting of a local torus action modeled on the standard representation (we call it a local torus action for simplicity) to a principal torus bundle, and sh…

Local torus actions modeled on the standard representation

Takahiko Yoshida

We introduce the notion of a local torus action modeled on the standard representation (for simplicity, we call it a local torus action). It is a generalization of a locally standa…

Twisted toric structures

Takahiko Yoshida

This paper introduces the notion of twisted toric manifolds which is a generalization of one of symplectic toric manifolds, and proves the weak Delzant type classification theorem…
