Counterexample to Barcilon’s Uniqueness Theorem for the Fourth-Order Inverse Spectral ProblemIn this paper, we construct a counterexample to the uniqueness
theorem by Barcilon (Geophys J Int
Regularization and Inverse Spectral Problems for Differential Operators with Distribution Coefficients. Furthermore, our regularization results are applied to inverse
spectral theory. We study a new type of inverse

Automorphisms of spectral lattices of positive contractions on von Neumann algebras© 2014, Pleiades Publishing, Ltd. We show that any
