Third-order operators with three-point conditions associated with Boussinesq's equation

Результат исследований: Научные публикации в периодических изданияхстатья


We consider a non-self-adjoint third-order operator on the interval [0, 2] with real 1-periodic coefficients and three-point Dirichlet conditions at the points 0, 1 and 2. The eigenvalues of this operator consist an auxiliary spectrum for the inverse spectral problem associated with the good Boussinesq equation. We determine eigenvalue asymptotics at high energy and the trace formula for the operator.
