Abstract

By using Liu's qq-partial differential equations theory, we prove that if an analytic function in several variables satisfies a system of qq-partial differential equations, if and only if it can be expanded in terms of homogeneous (q,c)(q,c)-Al-Salam-Carlitz polynomials. As an application, we proved that for c0c\neq0 and max{cq,x}<1\max \{|cq|,|x|\}<1, \begin{align*} \sum_{n=0}^{\infty} \frac{ (a;q)_n }{(cq;q)_n}x^n=(ax/c;q)_{\infty} \sum_{n=0}^{\infty} \frac{x^n}{(cq;q)_n}, \end{align*} which is a generalization of famous qq-binomial theorem or so-called Cauchy theorem.

Comments

The error in this manuscript is that the right side of equation (3.1) is not suitable for formula (1.1). This causes formula (3.1) to be incorrect. Therefore, theorem 1.2 is also incorrect. However, the second part of this manuscript about the theorem of q-partial differential equation theory is still the correct conclusion
