TY - JOUR AU - Wilson, B. M. AB - PSEUDO-ORTHOGONAL SYSTEMS OF FUNCTIONS. 59 ON PSEUDO-ORTHOGONAL SYSTEMS OF FUNCTIONS ARISING AS SOLUTIONS OF AN INTEGRAL EQUATION By B. M. WILSON. [Received 26 February, 1924.—Read 13 March, 1924. Received in revised form 27 January, 1925.] 1. IN a paper recently presented to the London Mathematical Society, Prof. Proudman has discussed the representation of an "arbitrary" function by a series of the type I,A v (x), where the functions v(x) are n n denned by means of the differential equation Xv{x) = 1 (0 1) j + ~ < *'< together with the boundary conditions (1 . 2) ©'(0) = ©(1) = 0, and the characteristic constants of the problem, ^•1 , ^-2, A3 , ..., are determined by the condition that (1.8) v f ©«(x) ( dx — a\ , n n J Jo o where a is a given real constant.* From equations (1.1), (1.2), and (1.3 ) it readily follows that (1.4) 1 v (x) v (x) dx = a (m =£ n). m n )o * J.
