SMOOTHNESS OF SUBHARMONIC FUNCTIONS

The smoothness of functions subharmonic in a domain D⊂Rn, n ≥ 2, is studied. The method for studying smoothness is based on the Riesz theorem on representation of a subharmonic function as the sum of a harmonic function and the potential Uμ(x) with respect to some Borel measure μ.
