Time and band limiting for exceptional polynomials
M. M. Castro, F. A. Grünbaum, I. Zurrián
The "time-and-band limiting" commutative property was found and exploited by D. Slepian, H. Landau and H. Pollak at Bell Labs in the 1960's, and independently by M. Mehta and later…
Reducibility of Matrix Weights
Juan Tirao, Ignacio Zurrián
In this paper we discuss the notion of reducibility for matrix weights and introduce a real vector space which encodes all information about the reducibilit…
Matrix Gegenbauer Polynomials: the Fundamental Cases
Inés Pacharoni, Ignacio Zurrián
In this paper, we exhibit explicitly a sequence of matrix valued orthogonal polynomials with respect to a weight , for any pair of real numbers and such…
Spherical Functions Associated With the Three Dimensional Sphere
Inés Pacharoni, Juan Tirao, Ignacio Zurrián
In this paper, we determine all irreducible spherical functions Φof any K -type associated to the pair (G,K)=(\SO(4),\SO(3)). This is accomplished by associating to Φa vector value…
