Isometric Embeddings and Hyperkähler Geometry of the Cotangent Bundle of Complex Projective Space via the Scheme of Rank-1 Projections

Joshua Lackman

We show that the hyperkahler geometry of can be described algebraically by the affine scheme of rank-1 projections, and that this description simultaneously…

A Geometric Definition of the Integral and Applications

Joshua Lackman

The standard definition of integration of differential forms is based on local coordinates and partitions of unity. This definition is mostly a formality and not used used in expli…

A Simple Description of the Hyperkähler Structure of the Cotangent Bundle of Projective Space via Quantization

Joshua Lackman

Quantization identifies the cotangent bundle of projective space with the (non-Hermitian) rank- projections of a Hilbert space. We use this identification to study the natural g…

Quantization of Holomorphic Symplectic Manifolds: Analytic Continuation of Path Integrals and Coherent States

Joshua Lackman

We extend Berezin's quantization to holomorphic symplectic manifolds, which involves replacing the state space with its comple…

On an Axiomatization of Path Integral Quantization and its Equivalence to Berezin's Quantization

Joshua Lackman

We axiomatize path integral quantization of symplectic manifolds. We prove that this path integral formulation of quantization is equivalent to an abstract operator formulation, ie…
