The theory of knotoids can be regarded as a refinement of classical knot theory. Knotoids provide a natural topological domain for studying the knotting of physical structures involving open-ended curves, for example, polymers. In analogy, braidoids extend the classical braids and they form a counterpart theory to the theory of knotoids. Any braidoid gives rise to a knotoid via the closure map and any knotoid can be turned into a braidoid whose closure is topologically equivalent to the starting knotoid. Braidoids can be used for encoding the topological information of knotoids in terms of algebraic expressions. View this paper
