comment Eigenvalues of the 1D laplacian with mixed boundary conditions
@GiuseppeNegro Thank you! It confirms my first intuition then. So I guess we cannot solve $u=\Delta u$ with such B.C. using the usual separation of variable method... Because when doing so, we decompose the solution along the eigenvectors, and here without a discrete spectrum I do not know how to do it.

comment Eigenvalues of the 1D laplacian with mixed boundary conditions
@GiuseppeNegro Hi, thanks for the hint; I tried this already. I find a zero eigenvalue (ok) but then I cannot exclude positive eigenvalues, and I do not get a discrete spectrum. So I believe I may be wrong.

comment Number of real solutions of a random equation
Dear Kirill, thank you a lot for your attempt. It looks like you are trying to apply Kac-Rice formula. But unfortunately I think your formula is missing the absolute value of the Jacobian determinant. Do you agree, or am I missing something ?
