Representation theory of the Lorentz group
The
Lorentz group
, a
Lie group
on which
special relativity
is based, has a wide variety of
representations
. Many of these representations, both finite-dimensional and infinite-dimensional, are important in
theoretical physics
in the description of
particles
in
relativistic quantum mechanics
, as well as of both particles and quantum fields in
quantum field theory
.
