Combinatorial classification of piecewise hereditary algebras
(De Gruyter, 2011-01)
We use the characteristic polynomial of the Coxeter matrix of an algebra to complete the combinatorial classification of piecewise hereditary algebras which Happel gave in terms of the trace of the Coxeter matrix. We also ...
Gaussian quadrature rules with simple node-weight relations
(Baltzer Sci Publ Bv, 2001-01-01)
In this paper, we consider the symmetric Gaussian and L-Gaussian quadrature rules associated with twin periodic recurrence relations with possible variations in the initial coefficient. We show that the weights of the ...
Polinômios Palindrômicos com Zeros somente Reais
(Universidade Estadual Paulista (Unesp), 2016-07-28)
Neste trabalho foi realizado um estudo sobre o comportamento dos zeros de polinômios palindrômicos, com foco nos zeros reais. Condições necessárias e suficientes para que um polinômio palindrômico com coeficientes reais ...

Coeficientes da relação de recorrência de polinômios ortogonais e equações de Painlevé
(Universidade Estadual Paulista (Unesp), 2020-02-28)
Neste trabalho estudamos a relação entre os coeficientes da relação de recorrência de alguns polinômios ortogonais semiclássicos e as equações discretas de Painlevé. Para isso consideramos uma propriedade importante de ...
