F-polynomials of tabulated virtual knots.

A sequence of F -polynomials { F K n (t , ℓ) } n = 1 ∞ of virtual knots K was defined by Kaur et al. in 2018. These polynomials have been expressed in terms of index value of crossing and n -writhe of K. By the construction, F -polynomials are generalizations of Kauffman's Affine Index Polynomial, and are invariants of virtual knot K. We present values of F -polynomials of oriented virtual knots having at most four classical crossings in a diagram. [ABSTRACT FROM AUTHOR]
