Polynomial Clones

Definition

Polynomial clones are sets of polynomial functions that share the same type of operations and allow for the generation of all polynomial functions from a given set of basic operations. They highlight the idea of completeness in terms of function generation, meaning that if you can create a polynomial function using a finite set of polynomial functions, then those functions can be considered part of a polynomial clone. This concept connects with various algebraic structures and their properties, especially concerning how different functions can be composed and represented within algebraic systems.
