Pascal-Brianchon Sets in Pappian Projective Planes

Vladimir Volenec ; Department of Mathematics, Faculty of Natural Sciences, University of Zagreb, Zagreb, Croatia

Abstract

It is well-known that Pascal and Brianchon theorems characterize conics in a Pappian projective plane. But, using these theorems and their modifications we shall show that the notion of a conic (or better a Pascal-Brianchon set) can be defined without any use of theory of projectivities or of polarities as usually.

Keywords
