BOUNDARY-BEHAVIOR OF SUBHARMONIC FUNCTIONS IN NONTANGENTIAL ACCESSIBLE DOMAINS

The following results concerning boundary behavior of subharmonic functions in the unit ball of R(n) are generalized to nontangential accessible domains in the sense of Jerison and Kenig [7]: (i) The classical theorem of Littlewood on the radial limits. (ii) Ziomek's theorem on the L(p)-nontangential limits. (iii) The localized version of the above two results and nontangential limits of Green potentials under a certain nontangential condition.
