A polynomial invariant of virtual magnetic link diagrams
Year: 2011
Type: article
Abstract: We introduce a polynomial invariant of virtual magnetic link\ndiagrams. For virtual links, this polynomial equals the polynomial\ninvariant defined in [3]. We show that it gives lower bounds\nof the classical crossing number and the virtual crossing\nnumber of virtual links. Also we give various properties of\nthis polynomial and examples.
