On Hankel Operators Associated with Markov Functions, we state results characterizing the rate of decrease of the sequence of singular numbers of the Hankel operator .. constructed from the Markov function with the measure . satisfying the Szegö condition: supp . = ⊂ (-1,1) and提炼 发表于 2025-3-22 12:21:11
Threshold Effects near the Lower Edge of the Spectrum for Periodic Differential Operators of Mathemfective mass, the effective Hamiltonian, etc. arise in these problems. We propose a general approach to these problems based on the spectral perturbation theory for operator-valued functions admitting analytic factorization. A great deal of considerations is done in abstract terms.中世纪 发表于 2025-3-22 13:33:45
Stabilization of irrational transfer functions by controllers with internal loop,al loop, called canonical and dual canonical controllers. We show that, in a certain sense, every stabilizing controller with internal loop is equivalent to a canonical controller, and also to a dual canonical controller.相同 发表于 2025-3-22 19:54:39

Higher-order Hankel forms and cohomology groups,e .th-order Hankel forms. We also use the decomposition to show that the map on the first order groups induced by the quotient map.is onto and the map induced by the inclusion of.into bounded bilinear forms is the zero map.有角 发表于 2025-3-23 07:44:50
Hardy spaces on a finite bordered Riemann surface, multivariable operator model theory and Fourier in context, we begin with the classical case, where the bordered Riemann surface is the closed unit disk .. We let .denote the unit circle, ε. denote a Hilbert space, and let . be the standard Lebesgue space of ..-valued, measurable functions . defined on . with .Then an arbitrary element . of .alte
