Following first attempts to make the mode-coupling theory (MCT) more quantitative, recently we showed [1]-[3] that the simple correction consisting in using an effective density in the MCT vertex significantly improved the quantitative predictions of the MCT, well beyond than time correlation functions. The justification of this correction from first principles should stimulate works about the MCT. The goal of the PhD work is to investigate this matter as well as comparisons to simulation data.
