• Separately continuous map
• Multi-value map
• Lower quasicontinuity
• Lower pseudo-quasicontinuity
• Lower covering categorical
• cliquishness

The paper introduces new concepts of lower pseudo-quasicontinuity and lower covering categorical cliquishness for multi-value maps and use them to set a general theorem on the points of jointly continuity of mappings f :X x Y -> Z, yielding as a partial case a previous result of the authors [9] as well as a result of A. Bouziad and J.P. Troallic [10].
