Berberyan, S. L. On angular boundary values of subharmonic functions from the class \(\mathcal N\). (English) Zbl 1274.30138 Math. Montisnigri 20-21, 5-14 (2007). Summary: We investigate the existence problem of angular boundary values of normal subharmonic functions in the unit disc at the points of the unit circle. Some well-known results are improved. Besides, for the first time, the paper gives some necessary and sufficient conditions for the existence of angular boundary values of normal subharmonic functions.
