With the help of methods of nonstandard analysis we investigate continuous convergencesin the space of multifunction sand describe pseudotopological algebras of continuous multifunctions.
The finite basis of identities of the varieties of the ordered algebras generated by partially ordered semigroups of binary relations with cylindrifications operations is found in this paper.
In the paper, the basis of identities for the variety generated by semigroups of relations with the operation of reflexive double cylindrification is found.
