    I can kinda see that p(x) will be smaller than L1 and larger than Ln, but I have no idea of how to prove it. As a side note; p(x) is really the rayleigh quotient.

    Please help, I sat up till very late last night, just looking at it without doing any progress :s

    for one way, how about trying replacing all the Li by Ln, noting Li>=Ln for all i?
