The Jones polynomial V-L(t) for an oriented link L is a one-variable Laurent polynomial link invariant discovered by Jones. For any integer n >= 3, we show that: (1) the difference of Jones polynomials for two oriented links which are C-n-equiv...

This article presents a survey of some recent results in the theory of spatial graphs. In particular, we highlight results related to intrinsic knotting and linking and results about symmetries of spatial graphs. In both cases we consider spatial ...

A neighborhood homotopy is an equivalence relation on spatial graphs which is generated by crossing changes on the same component and neighborhood equivalence. We give a complete classification of all 2-component spatial graphs up to neighborhood ...
