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


1. Differential Equation[-]

The function {P_{v}^{u}\left(x\right)} satisfies the differential equation with initial values y \left( 0 \right) =\frac{{2}^{u}\sin \left( \pi \, \left( 1/2-1/2\,u-1/2\,v \right) \right) \,\Gamma \left( 1/2+1/2\,u+1/2\,v \right) }{\sqrt {\pi } \left( -1 \right) ^{1/2\,u}\,\Gamma \left( 1+1/2\,v-1/2\,u \right) } and y' \left( 0 \right) =-\frac{{2}^{u}\left(1-u+v\right)\sin \left( \pi \, \left( -1/2\,u-1/2\,v \right) \right) \,\Gamma \left( 1+1/2\,u+1/2\,v \right) }{\sqrt {\pi } \left( -1 \right) ^{1/2\,u}\,\Gamma \left( 3/2+1/2\,v-1/2\,u \right) }.
All formulas on this page are valid under the condition that u and 2\,v are not integers (special values for parameters can be entered at the bottom).
