A note on biorthogonal ensembles
Abstract. We consider ensembles of random matrices, known as biorthogonal ensembles, whose eigenvalue probability density function can be written as a product of two determinants. These systems are closely related to multiple orthogonal functions. It is known that the eigenvalue correlation functions of such ensembles can be written as a determinant of a kernel function. We show that the kernel...
متن کاملA Vector Equilibrium Problem for Muttalib–Borodin Biorthogonal Ensembles
The Muttalib–Borodin biorthogonal ensemble is a joint density function for n particles on the positive real line that depends on a parameter θ. There is an equilibrium problem that describes the large n behavior. We show that for rational values of θ there is an equivalent vector equilibrium problem.
متن کاملRandom matrix ensembles involving Gaussian Wigner and Wishart matrices, and biorthogonal structure.
We consider four nontrivial ensembles involving Gaussian Wigner and Wishart matrices. These are relevant to problems ranging from multiantenna communication to random supergravity. We derive the matrix probability density, as well as the eigenvalue densities for these ensembles. In all cases the joint eigenvalue density exhibits a biorthogonal structure. A determinantal representation, based on...
متن کاملBiorthogonal partners and applications
Two digital filters ( ) and ( ) are said to be biorthogonal partners of each other if their cascade ( ) ( ) satisfies the Nyquist or zero-crossing property. Biorthogonal partners arise in many different contexts such as filterbank theory, exact and least squares digital interpolation, and multiresolution theory. They also play a central role in the theory of equalization, especially, fractional...
متن کاملBiorthogonal Wavelet Expansions
This paper is concerned with developing conditions on a given nite collection of compactly supported algebraically linearly independent reenable functions that insure the existence of biorthog-onal systems of reenable functions with similar properties. In particular we address the close connection of this issue with stationary subdivision schemes. 1 Introduction During the past few years the co...
