Computations on Some Hankel Matrices
Ruiming Zhang
In this note, we present the determinant, the inverse and a lower bound for the smallest eigenvalue for some Hankel matrices

Explicit Inversions of Certain Matrices II
Ruiming Zhang
In this note, we apply kernel polynomials to find the explicit inverses for some some Hankel matrices associated with q-orthogonal polynomials.

Explicit Inversions of Certain Matrices I
Ruiming Zhang
In this note, we demonstrate a method to invert some Hankel matrices explicitly by using the kernel polynomials for the related classical orthogonal polynomials.

On Generalized Hilbert Matrices
Ruiming Zhang
In this note, we present a systematic method to explicitly compute the determinants and inverses for some generalized Hilbert matrices associated with orthogonal systems with expli…
