Infinitely many two-variable generalisations of the Alexander-Conway polynomial
David De Wit, Atsushi Ishii, Jon Links
We show that the Alexander-Conway polynomial Delta is obtainable via a particular one-variable reduction of each two-variable Links-Gould invariant LG^{m,1}, where m is a positive…

The Links-Gould Invariant of Links
David De Wit, Louis H Kauffman, Jon R Links
We introduce and study in detail an invariant of (1,1) tangles. This invariant, derived from a family of four dimensional representations of the quantum superalgebra U_q[gl(2|1)],…
