With the exception of Secs. 1.4 and 1.5 on linear functionals, we list some terms and notations here for the sake of definiteness.
R and C denote the real and complex numbers with their usual topologies. F stands for either, without specifying which. R+ denotes the positive real numbers. Q, N, and Z denote the rationals, positive integers, and integers, respectively. “Iff” stands for if and only if. “Almost all” means “for all but a finite number.” The end of proofs, examples, etc. is marked with a .
