Verblunsky’s Theorem
… ►Szegő’s Theorem
►For as in (18.33.19) (or more generally as the weight function of the absolutely continuous part of the measure in (18.33.17)) and with the Verblunsky coefficients in (18.33.23), (18.33.24), Szegő’s theorem states that …2: 28.27 Addition Theorems
§28.27 Addition Theorems
►Addition theorems provide important connections between Mathieu functions with different parameters and in different coordinate systems. They are analogous to the addition theorems for Bessel functions (§10.23(ii)) and modified Bessel functions (§10.44(ii)). …3: 27.15 Chinese Remainder Theorem
§27.15 Chinese Remainder Theorem
►The Chinese remainder theorem states that a system of congruences , always has a solution if the moduli are relatively prime in pairs; the solution is unique (mod ), where is the product of the moduli. ►This theorem is employed to increase efficiency in calculating with large numbers by making use of smaller numbers in most of the calculation. …By the Chinese remainder theorem each integer in the data can be uniquely represented by its residues (mod ), (mod ), (mod ), and (mod ), respectively. …These numbers, in turn, are combined by the Chinese remainder theorem to obtain the final result , which is correct to 20 digits. …4: 30.10 Series and Integrals
