We determine all group homomorphisms SLn(D)
GLn(E), where D and E are division rings such that char D = char E and E is finite-dimensional over its centre. Apart from the case where n = 2 and D is F2 or F3, all non-trivial group homomorphisms SLn(D)
GLn(E) are induced from homomorphisms and anti-homomorphisms D
E.
