Let us define the following
\(\displaystyle \Gamma_q(x) = \frac{(q;\, q)_{\infty}}{(q^x;\,q)_{\infty}}(1-q)^{1-x}\)
Prove that
Naturally the q-beta function is defined as
\(\displaystyle B_q(x,y) = \frac{\Gamma_q(x)\Gamma_q(x)}{\Gamma_q(x+y)}\)
\(\displaystyle \Gamma_q(x) = \frac{(q;\, q)_{\infty}}{(q^x;\,q)_{\infty}}(1-q)^{1-x}\)
Prove that
\(\displaystyle \lim_{q \to 1^-}\Gamma_q(x)=\Gamma(x)\)
Naturally the q-beta function is defined as
\(\displaystyle B_q(x,y) = \frac{\Gamma_q(x)\Gamma_q(x)}{\Gamma_q(x+y)}\)
