Polinômios q-Ortogonais
(Universidade Estadual Paulista (Unesp), 2018-05-24)
O objetivo desta dissertação é estudar os chamados polinômios q-ortogonais. Com esse objetivo, analisamos algumas das igualdades envolvendo q-fatoriais, séries q-hipergeométricas e suas aplicações em certos polinômios ...
Semi- orthogonalities of class of Gauss hypergeometric functionsSemi- orthogonalities of class of Gauss hypergeometric functions
(2011-02-11)
We presented three semi-orthogonalities for a class of Gauss hypergeometric functions. We further employ the semi-orthogonalities to generate a theory concerning finite series expansion involving our hypergeometric functions.

Chapter 7: A further look at time-and-band limiting for matrix orthogonal polynomials
(World Scientific Publishing Co, 2018)
We extend to a situation involving matrix-valued orthogonal polynomials, a scalar result that originates in work of Shannon and a ground-breaking series of papers by Slepian, Landau and Pollak at Bell Labs in the 1960s. ...
Eigenvalue decay of integral operators generated by power series-like kernels
(ElementZagreb, 2014)
We deduce decay rates for eigenvalues of integral operators generated by power series-like kernels on a subset X of either 'R POT.Q' or 'C POT.Q'. A power series-like kernel is a Mercer kernel having a series expansion ...
Propiedades de algunos sistemas de polinomios ortogonales Sobolev en varias variables
(Universidad Nacional de ColombiaBogotá - Ciencias - Doctorado en Ciencias - MatemáticasDepartamento de MatemáticasFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2022-02-01)
En este trabajo estudiamos algunas propiedades algebraicas y analíticas de los polinomios ortogonales en varias variables reales con respecto a un producto interno Sobolev continuo-discreto. Consideramos los polinomios ...
Polinômios complementares de Romanovski-Routh e funções com ortogonalidade híbrida
(Universidade Estadual Paulista (Unesp), 2019-03-01)
Consideramos propriedades e aplicações dos polinômios complementares de Romanovski-Routh e de funções definidas em [-1,1] que satisfazem uma ortogonalidade híbrida. Estas funções estão relacionadas com uma certa classe de ...
Self-adjoint operators on inner product spaces over fields of power series
(WALTER DE GRUYTER GMBH, 2008)
Theorems on orthogonal decompositions are a cornerstone in the classical theory of real (or complex) matrices and operators on R-n. In the paper we consider finite dimensional inner product spaces (E,Phi) over a field K = ...
Orthogonal polynomials on the unit circle satisfying a second-order differential equation with varying polynomial coefficients
(Taylor & Francis Ltd, 2016-01-01)
Consider the linear second-order differential equation An(z) y+ B-n(z) y' + C(n)y = 0, where A(n)(z) = a(2), nz(2) + a(1,n)z + a(0), n with a(2), n = 0, a2 1, n - 4a2, na0, n = 0,. n. N or a2, n = 0, a1, n = 0,. n. N, Bn(z) ...
Model updating of the non-linear vibrating structures through Volterra series and proper orthogonal decomposition
(Katholieke Univ Leuven, Dept Werktuigkunde, 2012-01-01)
Classical procedures for model updating in non-linear mechanical systems based on vibration data can fail because the common linear metrics are not sensitive for non-linear behavior caused by gaps, backlash, bolts, joints, ...
