,Fourier Method for One-dimensional Schr?dinger Operators with Singular Periodic Potentials,By using quasi-derivatives, we develop a Fourier method for studying the spectral properties of one-dimensional Schr?dinger operators with periodic singular potentials.

Regularized Perturbation Determinants and KdV Conservation Laws for Irregular Initial Profiles,In the context of the Korteweg-de Vries equation we put forward some new conservation laws which hold for real initial profiles with low regularity. Some applications to spectral theory of the one-dimensional Schr?dinger operator with singular potentials are also considered.

The Gelfand-Levitan Theory for Strings, theory deals with Sturm-Liouville operators whose spectral functions behave like . or . only. The main tool here is the Gohberg-Krein special factorization of operators close to the identity, which gives a better insight on the existence of transformation operators of Volterra type.

,On the Uniqueness of a Solution to Anisotropic Maxwell’s Equations,×3 matrices. We formulate relevant boundary value problems, investigate a fundamental solution and find a Silver-Müller type radiation condition at infinity which ensures the uniqueness of solutions when permittivity and permeability matrices are real-valued, symmetric, positive definite and proportional ε = κμ, κ < 0.

Additive Invariants on Quantum Channels and Regularized Minimum Entropy, of its value is a positive lower bound for the regularized minimum entropy of an output quantum channel. We give a few examples in which one of these invariants is less than 1. We also study the special cases where the above both invariants are equal to 1.

A Functional Model, Eigenvalues, and Finite Singular Critical Points for Indefinite Sturm-Liouville Operators, point. An abstract approach to the problem is given via a functional model for indefinite Sturm-Liouville operators. Algebraic multiplicities of eigenvalues are obtained. Also, operators with finite singular critical points are considered.
