" A fuzzy description of Quantum Hall Physics "


Abstract


Noncommutative Chern-Simons action has been proposed as an effective 
description of the dynamics of infinite Quantum Hall samples projected 
into the lowest Landau level.  A special kind of regularization of this 
model gives rise to a matrix Chern-Simons theory, that can be used to 
describe finite droplets.  I will try to give a self-contained and 
physically motivated introduction to both noncommutative Chern-Simons 
theory and its matrix version, and their application to  Fractional 
Quantum Hall Effect.
