Abstract
Outlines of operational calculus i.e., techniques, reducing the solution of linear differential equations with constant coefficients to the solution of appropriate algebraic systems of linear equations, in differential algebras are described. It is shown that in the classical differential algebra such techniques cannot be realized, because of the lack of non-trivial exponentials. At the same time, the differential Lie algebra of vertical derivations, possesses a full spectrum of exponentials, and the corresponding operational calculus (secondary operational calculus )is developed.Footnote ∗
