Comparative quantizations of (2+1)-dimensional gravity.

We compare three approaches to the quantization of (2+1)dimensional gravity with a negative cosmological constant: reduced phase space quantization with the York time slicing, quantization of the algebra of holonomies, and quantization of the space of classical solutions. The relationships among these quantum theories allow us to define and interpret time-dependent operators in the “frozen time...

A method for 2-dimensional inversion of gravity data

Applying 2D algorithms for inverting the potential field data is more useful and efficient than their 3D counterparts, whenever the geologic situation permits. This is because the computation time is less and modeling the subsurface is easier. In this paper we present a 2D inversion algorithm for interpreting gravity data by employing a set of constraints including minimum distance, smoothness,...

Dimensional Reduction of Three Dimensional Gravity

Three dimensional Euclidean gravity in the dreibein-spin connection formalism is investigated. We use the monopole-instanton ansatz for the dreibein and the spin connection. We show that there is a solution for the equations of motion which has a degenerate metric in three dimensions. This solution corresponds to gravity on S. PACS: 04.20.-q , 04.60.-m

Quantizations of IR

Quantum real numbers are proposed by performing a quantum deformation of the standard real numbers IR. We start with the q-deformed Heisenberg algebra L̂q which is obtained by the Moyal ∗-deformation of the Heisenberg algebra generated by a and a. By representing L̂q as the algebras of q-differentiable functions, we derive quantum real lines from the base spaces of these functional algebras. We f...

Representations of Quantizations

1.1. Algebra case. Let A be a filtered quantization of a Z-graded finitely generated Poisson algebra A. By A -mod we denote the category of finitely generated A-modules. A basic tool to study such modules is to reduce them to finitely generated A-modules that can be studied by means of Commutative algebra/ Algebraic geometry. Given an A-module M , one introduces the notion of a good filtration ...
