We analyze the computability and the complexity of various definitions
of spectral radii for sets of matrices. We show that the joint and ge
neralized spectral radii of two integer matrices are not approximable
iu polynomial time, and that two related quantities-the lower spectral
radius and the largest Lyapunov exponent-are not algorithmically appr
oximable.
