Eigenvalue Problems for Nonlinear Differential Equations on a Measure Chain

Values of l are determined for which there exist positive solutions of the second order differential equation on a measure chain,uDD t.qla t.f u s t...s0, tg w0, 1x, satisfying either the conjugate boundary conditions u 0.su s 1..s0 or the right focal boundary conditions u 0.suD s 1..s0, where a and f are f x. f x. positive valued, and both lim xª0qx and lim xª`x exist.
