Representation
The representation of a Group 
on a Complex Vector Space 
is a group action of on by linear transformations. Two finite dimensional representations 
on and 
on 
are equivalentif there is an invertible linear map 
such that 
for all 
. is said to beirreducible if it has no proper Nonzero invariant Subspaces.
