Non-Hermitian Hamiltonians and Similarity Transformations
(Springer/Plenum Publishers, 2016-02)
We show that similarity (or equivalent) transformations enable one to construct non-Hermitian operators with real spectrum. In this way we can also prove and generalize the results obtained by other authors by means of a ...
Transformer Operation at Deep Saturation: Model and Parameter Determination
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INCPISCATAWAY, 2012)
This paper proposes a model that adequately describes the operation of the transformer at deep saturation, suitable for power-electronics applications, and a method for determining its parameters. Simulation and experimental ...
Approximation and the n-Berezin transform of operators on the Bergman space
(De Gruyter, 2005-07)
To any bounded operator S on the Bergman space La2 we associate a sequence of linear transforms Bn(S ) ∈ L∞(D), where n ≧ 0, and prove that the Toeplitz operators article image tend to S for some especial classes of operators ...
Variation operators for semigroups and Riesz transforms on BMO in the Schrödinger setting
(Springer, 2013-04)
In this paper we prove that the variation operators of the heat semigroup and the truncations of Riesz transforms associated to the Schrödinger operator are bounded on a suitable BMO type space.
Variation Operators for Semigroups and Riesz Transforms on BMO in the Schrödinger Setting
(Springer, 2012-06)
In this paper we prove that the variation operators of the heat semigroup and the truncations of Riesz transforms associated to the Schrödinger operator are bounded on a suitable BMO type space.
On the Weyl Transform with Symbol in the Gel'fand-Shilov Space and its Dual Space
(Universidad de La Frontera. Departamento de Matemática y EstadísticaUniversidade Federal de Pernambuco. Departamento de Matemática, 2010)
A generalization of the kinetic equation using the prabhakar-type operators
(Honam Mathematical Society, 2017)
Fractional kinetic equations are investigated in order to
describe the various phenomena governed by anomalous reaction in
dynamical systems with chaotic motion. Many authors have pro-
vided solutions of various families ...
Maximal operators, Riesz transforms and Littlewood–Paley functions associated with Bessel operators on BMO
(Academic Press Inc Elsevier Science, 2010-03)
In this paper we study boundedness properties of certain harmonic analysis operators (maximal operators for heat and Poisson semigroups, Riesz transforms and Littlewood–Paley g-functions) associated with Bessel operators, ...

(Elsevier Science, 2010-03)
In this paper we study boundedness properties of certain harmonic analysis operators (maximal operators for heat and Poisson semigroups, Riesz transforms and Littlewood– Paley g-functions) associated with Bessel operators, ...
Mapping properties of fundamental operators in harmonic analysis related to Bessel operators
(Polish Academy of Sciences. Institute of Mathematics, 2010-11)
We obtain sharp power-weighted L p , weak type and restricted weak type inequalities for the heat and Poisson integral maximal operators, Riesz transform and a Littlewood-Paley type square function, emerging naturally in ...
