On separately subharmonic and harmonic functions

“…For the notation, and for the definitions and properties of subharmonic functions, nearly subharmonic functions, quasinearly subharmonic functions (and quasinearly subharmonic functions n.s., too) etc., see e.g. [Br69], [He71], [Ta88], [RiTa93], [Ri07 4 ], [Ri08], [PaRi08], [Ri09], [PaRi09], [Ri11], and the references therein.…”
