“…For the past few years, the widespread application of lattice systems, such as in pattern formation, neural pulse propagation, and circuits, has drawn considerable attention from many researchers, for more detailed information, please refer to [18,19,20]. When ϵ 2 = 0, γ 2 = 0, the reversible Selkov lattice systems driven by white noises have been discussed by Wang, see [21]. Transforming a system (1)-( 2) with nonlinear noise interference into a deterministic reaction-diffusion equation (ϵ 1 = ϵ 2 = γ 1 = γ 2 = 0).…”

This paper is concerned with weak pullback mean random attractor of reversible Selkov lattice systems defined on the entire integer set \(\mathbb{Z}\) driven by locally Lipschitz Lévy noises. Firstly, we formulate the stochastic lattice equations to an abstract system defined in the non-concrete space \(\ell^2\times\ell^2\) of square-summable sequences. Secondly, we establish the global well-posedness of the systems with locally Lipschitz diffusion terms. Under certain conditions, we show that the long-time dynamics can be captured by a weakly compact and weakly attracting mean random attractor in the Bochner space \(L^2(\Omega,\ell^2\times\ell^2)\). To overcome the difficulty caused by the drift and diffusion terms, we adopt a stopping time technique to prove the convergence of solutions in probability. The mean random dynamical systems theory proposed by Wang (J. Differ. Equ., 31:2177-2204, 2019) is used to deal with the difficulty caused by the nonlinear noise.
