		Theorem 8 - Lyapunov polynomials are recurrence equations.
		The reason for forbidding Bell number diagram with a single partition in classification diagrams becomes clear, the terms are absent from the right hand side of the equation as they are the terms we wish to solve for.
		The derivatives in all other cases are indirectly inverse Bell polynomials, but in the case the derivatives are inverse Bell polynomials in their own right.

		An interesting demonstration of the power discrete mathematics is the importance of combinatorics in the study of the dynamics of continuous iteration.
		The Bell polynomials, which are related to set partitions, are the foundation of Continuous iteration of dynamical maps and the Stirling numbers of the first and second kind are also referenced.
		So I entered the integer sequence from summing the coefficients from the first step of my work into the OEIS and found out that I was working with the Bell polynomials, the derivatives of composite functions and isomorphic to the combinatoric structure set partitions, also known as the Bell numbers.

		A related problem Consider now the polynomial Qn(x) = EQ \i\su(k=0;n;) eq \b(\a\ac\hs4\co1(n;k))2 xk We have eq \x\le\ri(\a\ac\hs4\co5(Q0(x); Q1(x); Q2(x);...; Qn(x);Q1(x); Q2(x); Q3(x);...; Qn+1(x);Q2(x); Q3(x); Q4(x);...; Qn+2(x);...;...;...;...;...;Qn(x); Qn+1(x); Qn+2(x);...; Q2n(x))) = 2n xn(n+1)/2 I have already given [2] an analytic proof of that identity, but the following one is almost obvious.
		Bell polynomials Let us call Sm,k the Stirling number of the second kind, counting the equivalences with k classes over a set of n elements.
		Derangement polynomials Our last example is the derangement polynomial dn(x) = EQ \i\su(k=0;n;)(-1)k EQ \s\do2(\f(n!;k!)) xn-k Note that, indeed, dn(1) is the number of derangements, i.e.

		Two of them, by the author, are generalized to Bell polynomials.
		The first one results from an analytic theorem of Sylvester; the second one is a consequence of a direct factorization of the Hankel matrix.
		Another proof was given by Delsarte, using Charlier polynomials.
