On a measure space , the set of square integrable L2-functions is an -space. Taken together with the L2-inner product with respect to a measure , the -space forms a Hilbert space. The functions in an -space satisfy. The inequality ( 7) is called Schwarz's inequality . The basic example is when with Lebesgue measure.
