We consider the link between fragility and elasticity that follows fromanalysis of the data for a set of soft-colloid materials consisting ofdeformable spheres reported by Mattsson et. al., in Nature vol 462, 83 (2009).Fragility index for a soft-colloid is obtained from the density dependence ofthe long time relaxation near a so-called glass transition point. In addition,we fit data for the high frequency shear modulus for the respectivesoft-colloid to a corresponding theoretical expression for the same modulus.This expression for the elastic constant is in terms of the corresponding paircorrelation function for the liquid treated as of uniform density. The paircorrelation function is adjusted through a proper choice of the parameters forthe two body interaction potential for the respective soft-colloid material.The nature of correlation between the fragility and Poisson ratio observed forthe soft colloids is qualitatively different, as compared to the same formolecular glasses. The observed link between fragility of a metastable liquidand its elastic coefficients is a manifestation of the effects of structure ofthe fluid on its dynamics.
