Trace formulas for fourth order operators on unit interval, II
Pages: 217 – 239
We consider self-adjoint fourth order operators on the unit interval with the Dirichlet type boundary conditions. For such operators we determine few trace formulas, similar to the case of Gelfand–Levitan formulas for second order operators.
