Abstract :  With Neslihan Gugumcu we study invariants of knotoids (open ended knot diagrams with the endpoints in possibly different regions). These invariants include the bracket polynomial, the Turaev loop bracket polynomial (for planar knotoids), the arrow polynomial and a loop arrow polynomial. We discuss properties of these invariants, and with Dimos Goundaroulis and Sofia Lambropoulou we apply these techniques to the structure of open-ended polymer strings and to protein folding.
