Essay

The thesis is devoted to construction of the theory of invariant varieties of counteble systems differential and difference equations. Thentheorems of a reduction of an infinite systems of difference equations to a final systems, which is the linear extwnsion on the m-measured torus, are proved. The necessary conditions of existence of invariant tori of countable systems differential and difference equations are introduced.
