We introduce two sequences of two-variable polynomials Ln K (t, ℓ)}∞ n=1 and n K (t, ℓ)}∞ n=1, expressed in terms of index value of a crossing and n-dwrithe value of a virtual knot K, where t and l are variables. Basing on the fact that n-dwrithe is a flat virtual knot invariant, we prove that LKn and FKn are virtual knot invariants containing Kauffman affine index polynomial as a particular case. Using LK n we give sufficient conditions when virtual knot does not admit cosmetic crossing change. © 2018 World Scientific Publishing Company.
