title: A note on modelling with measures: two-features balance equations.
abstract: In this note we explain by an example what we understand by a balance situation and by a balance equation in terms of measures. The latter ones are an attempt to start modelling of (not only) diffusion-reaction or mass-conservation scenarios in terms of measures rather than by derivatives and other rates. By means of three examples this concept is extended to two-features (= two-traits-) balance situations, which, e.g., combine features like aging and physical motion in populations or physical motion and formation of polymers by means of a single model equation.
