Rezumat

The function f (the principal derivate operation) of algebra A is called parametrically expressible via a system of functions  of A, if there exists the functions g1; h1; :::; gm; hm which are expressed explicitly via  using superpositions, such that the predicate f (x1:::xn) = xn+1 is equivalent to the predicate 9t1:::9tk ((g1 = h1) ^ ::: ^ (gm = hm)) on the algebra A. Let us consider the pseudo-Boolean algebra hM;^;_;; :i, where  is relative pseudo-complement, and : is pseudo-complement.
