In integral calculus, Glasser's master theorem explains how a certain broad class of substitutions can simplify certain integrals over the whole real line from − ∞ {\displaystyle -\infty } to + ∞ . {\displaystyle +\infty .} The integrals in question must be construed as Cauchy principal values, and a fortiori it is applicable when the integral converges absolutely.
