Towards Noncommutative Quantization of Gravity
M. Heller, W. Sasin
We propose a mathematical structure, based on a noncommutative geometry, which combines essential aspects of general relativity and quantum mechanics, and leads to correct "limitin…
Emergence of Time
M. Heller, W. Sasin
In the groupoid approach to noncommutative quantization of gravity, gravitational field is quantized in terms of a C*-algebra A of complex valued funcions on a groupoid G (with con…
Dust in the Small Magellanic Cloud: Interstellar Polarization and Extinction
C. V. Rodrigues, A. M. Magalhaes, G. V. Coyne S. J. +1
To elucidate the dust properties in the SMC we have for the first time measured linear polarization in five colors in the optical region of the spectrum for a sample of reddened st…
Local and Global Properties of the World
Jacques Demaret, Michael Heller, Dominique Lambert
The essence of the method of physics is inseparably connected with the problem of interplay between local and global properties of the universe. In the present paper we discuss thi…
