The betweenness relation distinguishes non-similar pairs of concentric circles
Martin Doležal, Jan Kolář, Janusz Morawiec
Two subsets of the plane are betweenness isomorphic if there is a bijection such that, for every , the point lies on the line segment con…
Betweenness isomorphism classes of circles with finitely many points inside
Martin Doležal, Jan Kolář, Janusz Morawiec
We give a necessary and sufficient condition for two circles, each with finitely many points added inside, to be betweenness isomorphic. We fully characterize the betweenness isomo…
Extensions of vector-valued functions with preservation of derivatives
Martin Koc, Jan Kolář
Let and be Banach or normed linear spaces and a closed set. We apply our recent extension theorem for vector-valued Baire one functions arXiv:1512.03717 to obt…
Non-unique conical and non-conical tangents to rectifiable stationary varifolds in R^4
Jan Kolář
We construct a rectifiable stationary 2-varifold in R^4 with non-conical, and hence non-unique, tangent varifold at a point. This answers a question of L. Simon (Lectures on geomet…
