Explicit entropy bounds for symmetric nearest-neighbor subshifts
Vuong Bui
We provide another approach to Friedland's result that the topological entropy of a symmetric nearest-neighbor subshift is computable. Instead of the previous algebraic techniq…
A topological version of Hedetniemi's conjecture for equivariant spaces
Vuong Bui, Hamid Reza Daneshpajouh
A topological version of the famous Hedetniemi conjecture says: The mapping index of the Cartesian product of two -spaces is equal to the minimum of their $\mathbb Z/2…
An asymptotic lower bound on the number of polyominoes
Vuong Bui
Let be the number of polyominoes of cells and be Klarner's constant, that is, . We show that there exist some positive numbers $A…
Growth of bilinear maps III: Decidability
Vuong Bui
The following notion of growth rate can be seen as a generalization of joint spectral radius: Given a bilinear map with nonnegative c…
Growth of bilinear maps II: Bounds and orders
Vuong Bui
A good range of problems on trees can be described by the following general setting: Given a bilinear map and a vector $s\in\mathbb R…
On the joint spectral radius of nonnegative matrices
Vuong Bui
We give an effective bound of the joint spectral radius for a finite set of nonnegative matrices: For every , \[ \sqrt[n]{\left(\frac{V}{UD}\right)^{D} \max_C \max_{i…
A bound on the joint spectral radius using the diagonals
Vuong Bui
The primary aim of this paper is to establish bounds on the joint spectral radius for a finite set of nonnegative matrices based on their diagonal elements. The efficacy of this ap…
Growth of bilinear maps
Vuong Bui
For a bilinear map of nonnegative coefficients and a vector of positive entries, among an exponentially number o…
