Virtual strings

Abstract
A virtual string is a scheme of self-intersections of a closed curve on a surface. We study algebraic invariants of virtual strings as well as two equivalence relations on the set of strings: homotopy and cobordism. We also discuss connections between virtual strings and virtual knots
