Quasiregular mappings between equiregular SubRiemannian manifolds
Chang-Yu Guo, Sebastiano Nicolussi Golo, Marshall Williams +1
In this paper, we provide an alternative appraoch to an expectaion of Fässler et al [J. Geom. Anal. 2016] by showing that a metrically quasiregular mapping between two equiregular…
