The Smoluchowski coagulation equation is considered to be one of the most fundamental equations of the classical description of matter alongside the Boltzmann, Navier-Stokes and Euler equations. In this talk, we consider measure valued solutions to multicomponent coagulation equation and present new existence and mass conservation results.  The results hold for a generic class of coagulation kernels, including various kernels used in applications. After going through the main ideas of the proofs, we discuss in more detail how uniform spaces were used to obtain a candidate solution to the coagulation equation.
