Abstract:The notion of two-scale convergence for sequences of Radon measures with finite total variation is generalized to the case of multiple periodic length scales of oscillations. The main result concerns the characterization of $ (n+1)$-scale limit pairs $ (u,U)$ of sequences $ \{(u_\varepsilon{\mathcal{L}^N\!}_{\lfloor\Omega}, {Du_\varepsilon}_{\lfloor\O... ...cal{ M}(\Omega;\mathbb{R}^d)\times \mathcal{ M}(\Omega;\mathbb{R}^{d\times N})$ whenever $ \{u_\varepsilon\}_{\varepsilon>0}$ is a bounded sequence in $ BV(\Omega;\mathbb{R}^d)$. This characterization is useful in the study of the asymptotic behavior of periodically oscillating functionals with linear growth, defined on the space $ BV$ of functions of bounded variation and described by $ n\in\mathbb{N}$ microscales, undertaken in [10].
