 Title: On the sense preserving mappings in the Helm topology in the plane Authors: Pyrih, Pavel Keywords: Fine TopologyDensity Topology Issue Date: 1999 Publisher: Institute of Mathematics and Informatics Bulgarian Academy of Sciences Citation: Serdica Mathematical Journal, Vol. 25, No 1, (1999), 41p-46p Abstract: We introduce the helm topology in the plane. We show that (assuming the helm local injectivity and the Euclidean continuity) each mapping which is oriented at all points of a helm domain U is oriented at U.
