Q-difference polynomial
In combinatorial mathematics, the q-difference polynomials or q-harmonic polynomials are a polynomial sequence defined in terms of the q-derivative. They are a generalized type of Brenke polynomial, and generalize the Appell polynomials.

Q̵; Ꝗ; Ꝗꝗ; Ꝙ
Q with stroke (Ꝗ, ꝗ) is a letter of the Latin alphabet, derived from writing the letter Q with the addition of a bar through the letter's descender. The letter was used by scribes during the Middle Ages, where it was employed primarily as an abbreviationa modern parallel of this would be abbreviating the word "and" with an ampersand (&).
