An Efficient Symbolic Algorithm for Computing Lyapunov Constants in Planar Switching Systems
Cheng Zheng, Laigang Guo, Xiangyu Wang
Lyapunov constants are a crucial tool for analyzing bifurcation behavior in switching systems. This paper proposes an efficient algebraic symbolic algorithm for computing Lyapunov…
A Criterion for Equidistribution along the Function over Polynomial Sequences with Applications
Zhi Qi, Cheng Zheng
Let be a certain fixed homogeneous polynomial of integral coefficients. In this paper, we establish a quantitative equidistribution criterion for the ergodic av…

Let be a non-uniform lattice in . In this note, we show that there exists a constant such that for any , any one-parametrer un…
Translates of S-arithmetic orbits and applications
Uri Shapira, Cheng Zheng
We prove that certain sequences of periodic orbits of the diagonal group in the space of lattices equidistribute. As an application we obtain new information regarding the sequence…
Nonsingular (Vertex-Weighted) Block Graphs
Ranveer Singh, Cheng Zheng, Naomi Shaked-Monderer +1
A graph is \emph{nonsingular (singular)} if its adjacency matrix is nonsingular (singular). In this article, we consider the nonsingularity of block graphs, i.e., graphs…
Nonsingular Block Graphs: An Open Problem
Ranveer Singh, Cheng Zheng, Naomi Shaked-Monderer +1
A block graph is a graph in which every block is a complete graph. Let be a block graph and let be its (0,1)-adjacency matrix. Graph is called nonsingular (singular)…
Limiting Distributions of Translates of Divergent Diagonal Orbits
Uri Shapira, Cheng Zheng
We define a natural topology on the collection of (equivalence classes up to scaling of) locally finite measures on a homogeneous space and prove that in this topology, pushforward…
