Representations of flat virtual braids which do not preserve the forbidden relations

In the paper, we construct a representation ??? : FVBn -> Aut(F2n) of the flat virtual braid group FVBn on n strands by automorphisms of the free group F2n with 2n generators which does not preserve the forbidden relations in the flat virtual braid group. This representation gives a positive answer to the problem formulated by Bardakov in the list of unsolved problems in virtual knot theory and combinatorial knot theory by Fenn et al.Also we find the set of normal generators of the groups VPn boolean AND Hn in VBn, FVPn boolean AND FHn in FVBn, GVPn boolean AND GHn in GVBn, which play an important role in the study of the kernel of the representation ???.
