Supplemental Material: Aging of the Linear Viscoelasticity of Glass- and Gel-forming Liquids

We provide additional information regarding the solution of Eqs. (1)-(3) of the main text, which allows for the theoretical determination of both, the non-equilibrium zero-shear viscosity and and the t-evolving storage and loss moduli in glass and gel-forming liquids. In particular, we outline the main details involved in the solution of these equations for various specific cases, along with the procedure to quantitatively compare our theoretical results for these model systems with the experimental data.
