ON JOINTLY SOMEWHAT NEARLY CONTINUOUS FUNCTIONS
O. VANCSO
Abstract. 
This article answers three questions of Piotrowski (see Ref. 1) namely whether or not the separately somewhat, separately nearly or separately somewhat nearly continuity implies the jointly somewhat nearly continuity.\newline Further we investigate the weakening of the conditions of Piotrowski on the spaces $X$, $Y$, $Z$.
