Abstract
We study finite-dimensional semisimple complex representations of the universal lattices (). One may obtain such a representation by specializing to some complex values and composing the induced homomorphism with a rational representation of . We show that any semisimple representation coincides, on a subgroup of finite index, with a direct sum of tensor products of representations obtained in this way.
