The metric projections onto closed convex cones in a Hilbert space

Yanqi Qiu, Zipeng Wang

We study the metric projection onto the closed convex cone in a real Hilbert space $H$ generated by a sequence $V = {v_{n}}_{n = 0}^{\infty}$ . The first main result…

Hyper-positive definite functions II: A complete study of branching-Toeplitz operators

Yanqi Qiu, Zipeng Wang

We introduce and give a more or less complete study of a family of branching-Toeplitz operators on the Hilbert space $ℓ^{2} (T_{q})$ indexed by a rooted homogeneous tree $T_{q}$ of deg…

Radial Toeplitz operators and invariant determinantal point processes on Cayley trees

Yanqi Qiu

We give a complete description of bounded radial Toeplitz operators on the Hilbert space associated with a Cayley tree. As an application, we give a complete classification of a ri…
