Cool Math Behind Quantum MechanicsAdded:
The Parseval theorem says that you can map sequences in little L2 to functions in L2. And the Riesz-Fischer theorem says that you can map functions in L2 to sequences in little L2. Taken together, this means that L2 and little L2 are mathematically the same.
