x real variable.
z=x+\mathrm{i}y complex variable.

k,\ell,m,n integers.
s nonnegative integer.
\delta arbitrary small positive constant.
\Gamma\left(z\right) gamma function (§5.2(i)).
\psi\left(z\right) \ifrac{\Gamma'\left(z\right)}{\Gamma\left(z\right)}.

Unless indicated otherwise primes denote derivatives with respect to the variable.
