WebFeb 14, 2024 · Riesz-Fischer theorem A theorem establishing a relationship between the spaces $l_2$ and $L_2 [a,b]$: If a system of functions $\ {\phi_n\}_ {n=1}^\infty$ is orthonormal on the interval $ [a,b]$ (cf. Orthonormal system) and a sequence of numbers $\ {c_n\}_ {n=1}^\infty$ is such that $$\sum_ {n=1}^\infty c_n^2<\infty$$ WebTHE MEANING OF THE THEOREM This section will explain what Fisher’s theorem states. The following section will give the evidence showing that the meaning explained here is indeed what Fisher meant. Let M = the mean fitness in some population. (The precise definition of M will be given later.) Let dM = the change in M from time t to time t + dt.
