Polya's inequalities, global uniform integrability and the size of plurisubharmonic lemniscates

First we prove a. new inequality comparing uniformly the relative volume of a, Borel subset with respect to my given complex euclidean ball B subset of C-n with its relative logarithmic capacity in C-n with respect to the same ball B. An analogous comparison inequality for Borel subsets of euclidean balls of any generic real subspace of C-n is also proved. Then we give several interesting applications of these inequalities. First we obtain sharp uniform estimates on the relative size of plurisubhamionic lemniscates associated to the Lelong class of plurisubharmonic functions of logarithmic singularities at infinity on C-n as well as the Cegrell class of plurisubharmonic functions of bounded Monge-Ampere mass on a hyperconvex domain Omega subset of C-n. Then we also deduce new results on the global behaviour of both the Lelong class and the Cegrell class of plurisubharmonic functions.
