Abstract: In a recent paper, Allen and Swenberg investigated which link polynomials are capable of detecting causality in (2+1)-dimensional globally hyperbolic spacetimes. They ultimately suggested it is likely that the Jones Polynomial accomplishes this, while the Alexander-Conway polynomial, independently, is insufficient. As the Alexander-Conway polynomial on its own is not likely to detect causality an additional piece of information must be supplemented to the link polynomial. This paper aims to examine the ability of Alexander quandles, to distinguish the connected sum of two Hopf links and Allen-Swenberg Links. As the number of homomorphisms given by the Alexander quandles for the connected sum of Hopf links and the number of homomorphisms for the Allen-Swenberg Link are the same, we can conclude that the links are not distinguishable from one another using Alexander quandles and hence these quandles cannot capture causality when added to the Alexander-Conway polynomial.
