'Bosonization in 2+1 Dimensional CFT's'

Abstract:
We discuss recently formulated dualities between Chern-Simons-Matter CFT's
in 2+1 dimensions. These conjectured dualities relate Chern-Simons gauge
theories with fermionic matter to theories with bosonic matter. We'll 
briefly try
to illustrate different lines of research, in the high-energy and in the 
condensed
matter communities, leading to these surprising statements. We will then 
focus
the attention to the case of Abelian gauge theories, and show how to 
construct
a web of dualities 'composing' in a simple way the basic bosonizations. 
For instance
the boson-boson 'particle-vortex duality' of the 80's and a newly 
formulated
fermion-fermion duality can be proven in a couple of steps using some 
Abelian
bosonization.
