Abstract

Let r2r\geq 2 and (Xi,G)(X_i,G) (i=1,,r)(i=1,\cdots,r) be topological dynamical systems with GG being an infinite discrete amenable group. Suppose that πi:(Xi,G)(Xi+1,G)\pi_i:(X_i,G)\to (X_{i+1},G) are factor maps and 0wi10\leq w_i\leq 1. In this article, for fC(X1)f\in C(X_1), we introduce the weighted topological pressure Pa(f,G)P^{\textbf{a}}(f,G) for higher dimensions (not only for r=2r=2) of amenable group actions. By using measure-theoretical theory, we establish a variational principle as \begin{align*} P^{\textbf{a}}(f,G)=\sup_{\mu\in \mathcal{M}^G(X_1)}\Big(\sum_{i=1}^rw_ih_{\mu_i}(X_i,G)+w_1\int_{X_1}fd\mu\Big), \end{align*} where μi=πi1π1μ\mu_i=\pi_{i-1}\circ\cdots\circ\pi_{1}\mu is the induced GG-invariant measure on XiX_{i}.
