![_0F_1(;a;z)=lim_(q->infty)_1F_1(q;a;z/q).](/images/equations/ConfluentHypergeometricLimitFunction/NumberedEquation1.svg) |
(1)
|
It has a series expansion
![_0F_1(;a;z)=sum_(n=0)^infty(z^n)/((a)_nn!)](/images/equations/ConfluentHypergeometricLimitFunction/NumberedEquation2.svg) |
(2)
|
and satisfies
![z(d^2y)/(dz^2)+a(dy)/(dz)-y=0.](/images/equations/ConfluentHypergeometricLimitFunction/NumberedEquation3.svg) |

It is implemented in the Wolfram Language as Hypergeometric0F1[b,
z].
A Bessel function of the first kind
can be expressed in terms of this function by
![J_n(x)=((1/2x)^n)/(n!)_0F_1(;n+1;-1/4x^2)](/images/equations/ConfluentHypergeometricLimitFunction/NumberedEquation4.svg) |
