Some continuous operations on pairs of cliquish functions

The algebraic or lattice operations in the classes of cliquish or quasicontinuous functions are well known ([5, 8]). This also pertains to the symmetrical quasicontinuity or symmetrical cliquishness ([6]). In this article, we examine the superpositions F(f; g) where F is a contin- uous operation and f; g are cliquish (symmetrically cliquish) or f is con- tinuous (f is symmetrically quasicontinuous with continuous sections) and g is quasicontinuous (symmetrically quasicontinuous).
