Chapter 44 – Algebra of the Perrin Sequence and its Convolutions and Sequence Entanglement

Chapter44 (2)

The partial Bell Polynomial expresses polynomials of any order and is convenient to calculate parent sequences and convolutions.  The Perrin sequence is used as an example showing that a convolution hierarchy of sequences of various order can be algebraically equal.  The condition for algebraic equality is shown and how the calculus (derivatives) of these convolutions are determined. Linear mappings of the Parent and Element sequences are shown to be group homomorphisms.

Sequence entanglement of the element sequences is described. Entanglement is possible when the three  roots of the discriminant equation are real.
