Abstract
For measuring families of curves, or, more generally, of measures, -modulus is traditionally used. More recent studies use so-called plans on measures. In their fundamental paper \cite{ADS}, Ambrosio, Di Marino and Savaré proved that these two approaches are in some sense equivalent within . We consider the limiting case and show that the -modulus can be obtained alternatively by the plan approach. On the way, we demonstrate unexpected behavior of the -modulus in comparison with usual capacities and consider the relations between the --modulus and the --modulus.
