Planar Doodles: Their Properties, Codes and Classification

Andrew Bartholomew, Roger Fenn

We present those properties of planar doodles, especially when regarded as 4-valent graphs, that enable us to classify them into {\it prime} and {\it super prime} doodles by analog…

Doodles and commutator identities

Andrew Bartholomew, Roger Fenn, Naoko Kamada +1

A doodle is a collection of immersed circles without triple intersections in the -sphere. It was shown by the second author and P.~Tayler that doodles induce commutator identiti…

Alexander and Markov Theorems for Generalized Knots, I

Andrew Bartholomew, Roger Fenn

In this paper we look at which Alexander and Markov theories can be defined for generalized knot theories

Colorings and doubled colorings of virtual doodles

Andrew Bartholomew, Roger Fenn, Naoko Kamada +1

A virtual doodle is an equivalence class of virtual diagrams under an equivalence relation generated by flat version of classical Reidemesiter moves and virtual Reidemsiter moves s…

On Gauss codes of virtual doodles

Andrew Bartholomew, Roger Fenn, Naoko Kamada +1

We discuss Gauss codes of virtual diagrams and virtual doodles. The notion of a left canonical Gauss code is introduced and it is shown that oriented virtual doodles are uniquely p…

Doodles on surfaces

Andrew Bartholomew, Roger Fenn, Naoko Kamada +1

Doodles were introduced in [R. Fenn and P. Taylor, Introducing doodles, Topology of low-dimensional manifolds, pp. 37--43, Lecture Notes in Math., 722, Springer, Berlin, 1979] but…
