Asymptotics of the spectral data of perturbed Stark operators in the half-line with mixed boundary conditions
Julio H. Toloza, Alfredo Uribe
We obtain sharp asymptotic formulas for the eigenvalues and norming constants of Sturm-Liouville operators associated with the differential expression \[ -\frac{d^2}{dx^2} + x + q(…
The fast recurrent subspace on an -level quantum energy transport model
Jorge R. Bolaños-Servín, Josué I. Rios-Cangas, Alfredo Uribe
The fast recurrent subspace (the biggest support of all invariant states) of a Weak Coupling Limit Type Quantum Markov Semigroup modeling a quantum transport open system of -ene…
The Dirichlet problem for perturbed Stark operators in the half-line
Julio H. Toloza, Alfredo Uribe
We consider the perturbed Stark operator , , in , where is a real-valued function that belongs to $\mathfrak{A}_r =\left\{ q\i…
One-dimensional Stark operators in the half-line
Julio H. Toloza, Alfredo Uribe
We obtain asymptotic formulas for the spectral data of perturbed Stark operators associated with the differential expression \[ -\frac{d^2}{dx^2} + x + q(x), \quad x\in [0,\infty),…
Oversampling and aliasing in de Branges spaces arising from Bessel operators
Julio H. Toloza, Alfredo Uribe
We show that a class of de Branges spaces, generated by means of generalized Fourier transforms associated with perturbed Bessel differential equations, has the properties of overs…
Oversampling and undersampling in de Branges spaces arising from regular Schrödinger operators
Luis O. Silva, Julio H. Toloza, Alfredo Uribe
The classical results on oversampling and undersampling (or aliasing), of functions in Paley-Wiener spaces, are generalized to the case of functions in de Branges spaces arising fr…
