Abstract: Abstract R.A. Rao–W. van der Kallen showed that the Vaserstein symbol V Γ ( S R 3 ) from the orbit space of unimodular rows of length three over the coordinate ring of the real… read more here.

Abstract: In this paper we study the non-injectivity arising in infinite interval exchange transformations. In particular, we build and analyze an infinite family of infinite interval exchanges semi-conjugated to generalized Thue-Morse subshifts, whose non-injectivity occurs at… read more here.
