The Special Function {Q_{v}^{u}\left(x\right)}


1. Differential Equation[-]

The function {Q_{v}^{u}\left(x\right)} satisfies the differential equation with initial values y \left( 0 \right) =\frac{{2}^{u-1}\sqrt {\pi }\,\Gamma \left( 1/2+1/2\,u+1/2\,v \right) }{{{\rm e}^{1/2\,i\pi \, \left( -2\,u+v+1 \right) }}\,\Gamma \left( 1+1/2\,v-1/2\,u \right) } and y' \left( 0 \right) =\frac{\sqrt {\pi }{2}^{u}\,\Gamma \left( 1+1/2\,u+1/2\,v \right) }{{{\rm e}^{1/2\,i\pi \, \left( -2\,u+v \right) }}\,\Gamma \left( 1/2\,v-1/2\,u+1/2 \right) }.
