“…The eigenfunction u is not random in this case because the eigenvalue X and the coefficients ak combine in just the right manner to eliminate the randomness in u. This case was treated in a paper by The general eigenvalue problem has been formulated and studied in different ways by Boyce [2,3,4,5,6,9], Goodwin [6,9], Haines [10], Purkert and vom Scheidt [12] and others. In the survey paper of Boyce [3], an asymptotic method is mentioned briefly for determining the eigenvalues and eigenfunctions of a randomly perturbed problem.…”
