On a class of random sets of positive integers
Yong Han, Yanqi Qiu, Zipeng Wang
In this note, we study a class of random subsets of positive integers induced by Bernoulli random variables. We obtain sufficient conditions such that the random set is almost sure…
Toeplitz operators between distinct Bergman spaces
Siyu Wang, Zipeng Wang
For , let be the standard weight on the unit disk. In this note, we provide descriptions of the boundedness and compactness for the Toeplitz…
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 indexed by a rooted homogeneous tree of deg…
Hyper-positive definite functions I: scalar case, branching-type stationary stochastic processes
Yanqi Qiu, Zipeng Wang
We propose a definition of branching-type stationary stochastic processes on rooted trees and related definitions of hyper-positivity for functions on the unit circle and functions…
Control of ecological outcomes through deliberate parameter changes in a model of the gut microbiome
Zipeng Wang, Eric W. Jones, Joshua M. Mueller +1
The generalized Lotka-Volterra (gLV) equations are a mathematical proxy for ecological dynamics. We focus on a gLV model of the gut microbiome, in which the evolution of the gut mi…
On the Controllability of Lagrangian Systems by Active Constraints
Alberto Bressan, Zipeng Wang
We consider a mechanical system which is controlled by means of moving constraints. Namely, we assume that some of the coordinates can be directly assigned as functions of time by…
