“…Roughly speaking, q-calculus analyzes q-analogues of mathematical concepts and formulas that can be recaptured by the limit q → 1. The concepts of q-calculus are extensively applied in various subjects of physics and mathematics, including combinatorics, number theory, orthogonal polynomials, geometric function theory, quantum theory and mechanics, and the theory of relativity; see [3][4][5][6][7][8][9].…”
