- Consideration of the simplest case of 2x2 diagonal
- matrices suggests that the problem as stated has no solutions.
-
- One may however try to generalize the problem to the
- case where a single matrix entry is carried, not by one,
- but by many group elements.
-
- e.g. G a group, E a partition of G, E* a subset of E
-
- f : {1..N}x{1..N} -> E* one to one
-
- c : E-E* -> F, F a field
-
-
- p(M)(g) = Mij if g in f(i,j)
- = c(class of g) else
-
-
- There are probably other ways to look into. My question
- boils down to : are there any (standard, simple) ways
- to construct endomorphisms from matrix algebra into
- group algebra ?
