--------------------------------------- Explicit Generating Functions, Asymptotics, and More for the "Mixed" Moments\ of Rudin-Shapiro polynomials up to, 7 By Shalosh B. Ekhad (ShaloshBEkhad@gmail.com ) Let , P[k](z), be the Rudin-Shapiro polynomial as described for example, in:\ https://en.wikipedia.org/wiki/Shapiro_polynomials . The best way to define them is via the recurrence 2 2 P[k](z) = P[k - 1](z ) + z P[k - 1](-z ) Let m, n and k be a positive integers, and define, with Hugh Montgomery (in \ Oberwolfach) https://www.mfo.de/document/1343/OWR_2013_51.pdf (see pp. 67-68) 1 / | m n M[m, n](k) = | P[k](exp(2 I Pi t)) P[k](exp(-2 I Pi t)) dt | / 0 It turns out (from our approach) that, for every specific positive integers \ m and n, the generating function of the sequence M[m,n](k) infinity ----- \ k f[m, n](t) = ) M[m, n](k) t / ----- k = 0 is always a rational function of t. Here we will derive these generating functions, fully rigorously, for all 1<\ m
