Usando como hilo conductor la recuperación y superación del legado matemático -y científico- griego, se analizarán en esta colaboración cuatro importantes efemérides matemáticas: la muerte de Thābit ibn Qurra (901), los nacimientos de Gerola

Exceptional Laguerre and Jacobi polynomials p n ( x ) p_n(x) are bispectral, in the sense that as functions of the continuous variable x x , they are eigenfunctions of a second order differential operator and as functions of the discrete variable n n

We prove a partial fraction decomposition of a quotient of two functions E α ( i t x ) and I α ( i t ) which are defined in terms of the Bessel functions J α and J α + 1 of the first kind. This expansion leads naturally to the introduction of an

Given a finite set F = { f 1 , ⋯ , f k } of nonnegative integers (written in increasing order of magnitude) and a classical discrete family ( p n ) n of orthogonal polynomials (Charlier, Meixner, Krawtchouk or Hahn), we consider the Casorati determ

Given a finite set of positive integers G and polynomials Rg, g∈G, with degree of Rg equal to g, we associate to them a sequence (qn(x))n of Charlier type polynomials defined from the Charlier poly...

Krall–Charlier polynomials ( c n a ; F ) n are orthogonal polynomials which are also eigenfunctions of a higher order difference operator. They are defined from a parameter a (associated to the Charlier polynomials) and a finite set F of positive i
