Self adjoint form

WebThe operator is not self-adjoint, with p0 = x and p1 = 1 − x. But we can form (8.22) The boundary terms, for arbitrary eigenfunctions u and v, are of the form their contributions at x = ∞ vanish because u and v go to zero; the common factor x … Web1.5 Self-adjointness and expansion in eigenvectors Sometimes an operator is its own adjoint, in which case its called self-adjoint. Self-adjoint operators have some very nice properties which we will exploit. The most important are 1. The eigenvalues are real. 2. The eigenvectors corresponding to different eigenvalues are orthogonal.
