Abstract
We introduce a polynomial invariant of long virtual knots that is non-trivial for many virtual knots, but is trivial on classical knots. Also this polynomial is sometimes useful for finding the virtual crossing number of long virtual knots. We give various properties of this polynomial and examples.
