The centre symmetry set

Peter Giblin, Paul Holtom (1999)

Banach Center Publications

Similarity:

A centrally symmetric plane curve has a point called it’s centre of symmetry. We define (following Janeczko) a set which measures the central symmetry of an arbitrary strictly convex plane curve, or surface in R 3 . We investigate some of it’s properties, and begin the study of non-convex cases.

Some remarks on duality in S 3

Ian Porteous (1999)

Banach Center Publications

Similarity:

In this paper we review some of the concepts and results of V. I. Arnol’d [1] for curves in S 2 and extend them to curves and surfaces in S 3 .
