How round is a circle? Constructions of double and circular planar near-rings

Stefan Veldsman

Department of Mathematics, Sultan Qaboos University, PO Box 35, Al-Khod PC123, Sultanate of Oman, e-mail: veldsman@squ.edu.om

Abstract: A construction procedure for planar near-rings is provided. Amongst others, this method will show why many planar near-rings come in pairs with ``opposite'' geometries and it will also lead to the construction of many new infinite circular planar near-rings.
