Abstract: In this paper we study the locally uniform convergence of homeomorphisms with bounded $(1,\sigma)$-weighted $(q,p)$-distortion to a limit homeomorphism. Under some additional conditions we prove that the limit homeomorphism is a mapping with bounded $(1,\sigma)$-weighted $(q,p)$-distortion. Moreover, we obtain the property of lower semicontinuity of distortion characteristics of homeomorphisms.

Keywords: semicontinuity from below, homeomorphism with bounded $(1,\sigma)$-weighted $(q,p)$-distortion, Carnot group.
