A note on weakly discontinuous dynamical transitions

We analyze mode coupling discontinuous transition in the limit of vanishing discontinuity, approaching the so called "A(3)" point. In these conditions structural relaxation and fluctuations appear to have universal form independent from the details of the system. The analysis of this limiting case suggests new ways for looking at the mode coupling equations in the general case. (C) 2013 American Institute of Physics. [http://dx.doi.org/10.1063/1.4790517]
