The Gaussian integral, also called the probability integral and closely related to the erf function, is the integral of the one-dimensional Gaussian function over (-infty,infty). I heard about it from Michael Rozman [14], who modi ed an idea on math.stackexchange [22], and in a slightly less elegant form it appeared much earlier in [18]. An integral domain is a commutative ring with identity and no zero-divisors.
