x_{1} is the Dirac delta function (generalized), defined on structure x_{2} (contextless default is probably the field of real numbers), yielded by family of distributions x_{3} (contextless default is probably Gaussians centered at
0 and which enclose unit area)

This generalized function evaluates to zero (0) everywhere except at 0 (in the domain), at which it evaluates to an infinity (∞) sufficient(ly large) for the purpose of integration to exactly equal one (1) whenever the integral interval properly contains 0 (in the domain). x2 determines what 0, 1, and ∞ mean. Properly, more than a set should be specified; the domain and codomain are determined thereby.
