Abstract: On the set of functions of $k$-valued logic, a closure under composition operation and light version of inversion operation is considered. The cardinality of the set of all such closed classes is calculated.

Key words: $k$-valued logic, closed classes, closure operator, inversion operation, extension of composition operation.
