Integral Representations

If Re b > Re a > 0, M(a,b,z) can be represented as an integral

thus is the characteristic function of the beta distribution. For a with positive real part U can be obtained by the Laplace integral

The integral defines a solution in the right half-plane re z > 0.

They can also be represented as Barnes integrals

where the contour passes to one side of the poles of Γ(−s) and to the other side of the poles of Γ(a+s).

Famous quotes containing the word integral:

    An island always pleases my imagination, even the smallest, as a small continent and integral portion of the globe. I have a fancy for building my hut on one. Even a bare, grassy isle, which I can see entirely over at a glance, has some undefined and mysterious charm for me.
    Henry David Thoreau (1817–1862)
