In this paper ,the author discussed the invariant of the virtual knots and links. According to the defini-tions and properties of classic knots,the author studied the Jones Polynomials of virtual knots and links,andproved that it is an invariant under extended Reidemeister moves.After that,by reading the document [1]the author discussed the Conway Polynomial for virtual knots and links from the case of skein-relation,andunder this kind of algorithm the author gave the basement relations of the virtual knots and links which havethe crossing number less than or equals to 5. |
