ON COLORED QUANDLE LONGITUDES AND ITS APPLICATIONS TO TANGLE EMBEDDINGS AND VIRTUAL KNOTS
Abstract
Given a long knot diagram D and a finite quandle Q, we consider the set of all quandle colorings of D with a fixed color q of its initial arc. Using this set we define the family of quandle automorphisms which is a knot invariant. For every element x ∈ Q one can consider the formal sum
, taken over all
. Such formal sums can be applied to a tangle embedding problem and recognizing non-classical virtual knots.
