Abstract: I will present my multivariate Alexander polynomial, which also generalizes to a tangle invariant. I'll discuss the algorithm and proof that our algorithm is in fact the multivariate Alexander polynomial defined by Conway in 1970. This multivariate calculation generalizes Professor Stephen Bigelow's diagrammatic method for calculating the single variable Alexander polynomial of a knot or link.
