The Special Function  {D_{a}\left(x\right)}


1. Differential Equation[-]

The function  {D_{a}\left(x\right)} satisfies the differential equation with initial values y \left( 0 \right) =\frac{{2}^{1/2\,a}\sqrt {\pi }}{\Gamma  \left( 1/2-1/2\,a \right) } and y' \left( 0 \right) =-\frac{{2}^{1/2\,a}\sqrt {\pi }\sqrt {2}}{\Gamma  \left( -1/2\,a \right) } .
