Another of these is de ned through a skein relation and takes the value of 1 on the unknot; that one is named for Jones.
One of these things is equal to the graded Euler characteristic of a Floer homology of Ostváth and Szabó. A paper by Edward Witten entitled  Quantum Field Theory  and [one of these things] showed that two of these things have correspondences to Chern-Simons gauge theory. One of these things is in two variables and is named for its six discoverers; that one of these things is the   HOMFLY [read as: hom- ea] one. The  rst-discovered one of these things is symmetric and named for Alexander. Another of these is de ned through a skein relation and takes the value of 1 on the unknot; that one is named for Jones. For ten points, identify these algebraic objects which are used as invariants to describe knots.
