Asymptotic approximations for a new eigenvalue in linear problems without a threshold
D. E. Pelinovsky, C. Sulem University of Toronto
Abstract:
We study the criterion for a new eigenvalue to appear in the linear spectral problem associated with the intermediate long-wave equation. We compute the asymptotic value of the new eigenvalue in the limit of a small potential using a Fourier decomposition method. We compare the results with those for the Schrödinger operator with a radially symmetrical potential.
