Functions studied have integer polynomial restrictions to finite integer sets
Such functions form a commutative ring containing integer polynomials
They are characterized by integer sequences and bijections of naturals
The ring contains units -1 and 1 and is closed under composition
Bounds relate growth rate of these functions to degree of polynomials
Integer-valued functions defined locally by integer polynomials
This paper introduces an interesting class of integer-valued functions on the integers. These functions have the property that their restriction to any finite subset of the integers is given by a polynomial with integer coefficients. The paper studies properties of this class of functions, which form a commutative ring containing the integer polynomials. Key results characterize these functions, show they are closed under composition and discrete derivatives, and investigate bounds on their growth rates.
