A similar result holds for the rising factorial and the backward difference operator. The study of analogies of this type is known as umbral calculus. A general theory covering such relations, including the falling and rising factorial functions, is given by the theory of polynomial sequences of binomial type and Sheffer sequences. Falling and ...
Stirling numbers express coefficients in expansions of falling and rising factorials (also known as the Pochhammer symbol) as polynomials.. That is, the falling factorial, defined as = (+) , is a polynomial in x of degree n whose expansion is
In mathematics, the (signed and unsigned) Lah numbers are coefficients expressing rising factorials in terms of falling factorials and vice versa. They were discovered by Ivo Lah in 1954. [1] [2] Explicitly, the unsigned Lah numbers (,) are given by the formula involving the binomial coefficient
One special case of these bracketed coefficients corresponding to allows us to expand the multiple factorial, or multifactorial functions as polynomials in . [ 22 ] The Stirling numbers of both kinds, the binomial coefficients , and the first and second-order Eulerian numbers are all defined by special cases of a triangular super-recurrence of ...

The Stirling numbers of the first kind may be characterized as the numbers that arise when one expresses powers of an indeterminate x in terms of the falling factorials [3] = () (+). (In particular, (x) 0 = 1 because it is an empty product.)
Variable rates work by rising or falling in reaction to financial markets. Typically, they’re tied to a benchmark rate, such as the Wall Street Journal Prime Rate and the Secured Overnight ...
