We study exact results concerning the non-afﬁne displacement ﬁelds observed by Tanguy et al. [Europhys. Lett.57, 423 (2002), Phys. Rev. B66, 174205 (2002)] and their contributions to elasticity. A normal mode analysis permits us to estimate the dominant contributions to the non-afﬁne corrections to elasticity and relate these corrections to the correlator of a ﬂuctuating force ﬁeld. We extend this analysis to the visco-elastic dynamical response of the system.
