Li-Yorke and Devaney chaotic uniform dynamical systems amongst weighted shifts

In this paper, for finite discrete field $F$, nonempty set $\Gamma$, weight vector $\mathfrak{w}=({\mathfrak w}_\alpha)_{\alpha\in\Gamma}\in F^\Gamma$ and weighted generalized shift $\sigma_{\varphi,{\mathfrak w}}:F^\Gamma\to F^\Gamma$, we find necessary and sufficient conditions for uniform dynamical system $(F^\Gamma,\sigma_{\varphi,{\mathfrak w}})$ to be Li--Yorke chaotic. Next we find necessary and sufficient conditions for $(F^\Gamma,\sigma_{\varphi,{\mathfrak w}})$ to be Devaney chaotic.
