Verblunsky parameters and linear spectral transformations [PDF]
, 2009 18 pages, no figures.-- MSC2000 codes: 42C05.In this paper we analyze the behavior of Verblunsky parameters for hermitian linear functionals deduced from canonical linear spectral transformations of a quasi-definite hermitian linear functional.

Three-Hilbert-Space Formulation of Quantum Mechanics [PDF]
, 2009 In paper [Znojil M., Phys. Rev. D 78 (2008), 085003, 5 pages, arXiv:0809.2874] the two-Hilbert-space (2HS, a.k.a. cryptohermitian) formulation of Quantum Mechanics has been revisited. In the present continuation of this study (with the spaces in question

Determinism and a supersymmetric classical model of quantum fields [PDF]
, 2005 A quantum field theory is described which is a supersymmetric classical model. -- Supersymmetry generators of the system are used to split its Liouville operator into two contributions, with positive and negative spectrum, respectively.

Some remarks on the GNS representations of topological $^*$-algebras [PDF]
, 2008 After an appropriate restatement of the GNS construction for topological $^*$-algebras we prove that there exists an isomorphism among the set $\cycl(A)$ of weakly continuous strongly cyclic $^*$-representations of a barreled dual-separable $^*$-algebra ...

Quasiparticle properties in a density functional framework [PDF]
, 2006 We propose a framework to construct the ground-state energy and density matrix of an N-electron system by solving selfconsistently a set of single-particle equations.

Stochastic dynamics of determinantal processes by integration by parts [PDF]
, 2014 We derive an integration by parts formula for functionals of determinantal processes on compact sets, completing the arguments of [4]. This is used to show the existence of a configuration-valued diffusion process which is non-colliding and admits the ...

Turning the Quantum Group Invariant XXZ Spin-Chain Hermitian: A Conjecture on the Invariant Product
, 2007 This is a continuation of a previous joint work with Robert Weston on the quantum group invariant XXZ spin-chain (math-ph/0703085). The previous results on quasi-Hermiticity of this integrable model are briefly reviewed and then connected with a new ...

Self-Consistent Separable Rpa Approach for Skyrme Forces: Axial Nuclei [PDF]
, 2005 The self-consistent separable RPA (random phase approximation) method is formulated for Skyrme forces with pairing. The method is based on a general self-consistent procedure for factorization of the two-body interaction.

Representations of hermitian kernels by means of Krein spaces II. Invariant kernels
, 2000 In this paper we study hermitian kernels invariant under the action of a semigroup with involution. We characterize those hermitian kernels which realize the given action by bounded operators on a Krein space.
