Molecular dynamics simulations of a Lennard-Jones binary mixture confined in a disordered array of soft spheres are presented. The single particle dynamical behavior of the glass former is examined upon supercooling. Predictions of mode coupling theory are satisfied by the confined liquid. Estimates of the crossover temperature are obtained by power law fit to the diffusion coefficients and relaxation times of the late α region. The b exponent of the von Schweidler law is also evaluated.

... ly to the bulk, different values of the exponent γ are extracted from the power law fit to the diffusion coefficients and relaxation times.
