Quasiconformal Whitney Partition
Vladimir Gol'dshtein, Nahum Zobin
Whitney partition is a very important concept in modern analysis. We discuss here a quasiconformal version of the Whitney partition that can be usefull for Sobolev spaces.
On planar Sobolev -extension domains
Pavel Shvartsman, Nahum Zobin
For each and we characterize bounded simply connected Sobolev -extension domains . Our criterion is expressed in terms of certain intrinsic subh…
Failure of the Weierstrass Preparation Theorem in quasi-analytic Denjoy-Carleman rings
Francesca Acquistapace, Fabrizio Broglia, Michail Bronshtein +2
It is shown that Denjoy-Carleman quasi-analytic rings of germs of functions in two or more variables fail to satisfy the Weierstrass Preparation Theorem. The result is proven via a…
Fubctional integral approach to quantum gauge theories on a noncommutative space-time
Nahum Zobin
We propose a construction of actions of a quantum gauge field theory on a noncommutative space-time, based on a Fourier transform on the Doplicher-Fredenhagen-Roberts group. This a…
Noncommutative Gauge Theory without Lorentz Violation
Carl E. Carlson, Christopher D. Carone, Nahum Zobin
The most popular noncommutative field theories are characterized by a matrix parameter theta^(mu,nu) that violates Lorentz invariance. We consider the simplest algebra in which the…
