From Terry Tao Blog, Vaughan Jones who made fundamental contributions in operator algebras and knot theory (in particular developing a surprising connection between the two), died this week, aged 67.

Question What are the known results and unpublished results of Vaughan Jones in mathematics ? and what do you like in the mathematics of Vaughan Jones?

Addendum :This part is directed to his students and his colleagues .As @ Jon Bannon suggested and pointed out in the comments ,Since Vaughan Jones was a very creative mathematician we may get from Vaughan Jones students or by his colleagues the state of the art of his vision? And how Vaughan Jones seen the applications of planar algebra in Quantum theory should be? The best example is the reformulation of Riemann hypothesis using planar algebra more than that How Vaughan Jones see the connection between planar algebra and number theory should being to solve biggest open problems in pure mathematics like Riemann hypothesis and irrationality measure of pi?
