Two linear representations of a group over a field are said to be locally conjugate if for any element of the group, its image under the two representations defines equivalent linear transformations (in particular, if we identify the vector spaces on which the representations are there, its images must be conjugate).
Definition with symbols
Let be a group and a field.
Two linear representations and of over are locally conjugate if for any , there exists such that:
Definition using the L-map
where is the union of the set of conjugacy classes in for all vector spaces over .
Then, we say that two representations and are locally conjugate with respect to if for any :
Note that though the above is described in terms of indecomposable linear representation, we can define the -map for arbitrary linear representations, and the same definition can thus be used to call two arbitrary linear representations locally conjugate.
