Arithmetic and congruence links

If M is a closed orientable 3 manifold and L a link in M, then L is called arithmetic if M\ L is an arithmetic hyperbolic 3-manifold. The link is called congruence if M\ L is a congruence arithmetic hyperbolic 3-manifold. This talk will be concerned with arithmetic and congruence links in 3-manifolds, and in particular we are motivated by the question: Are there infinitely many congruence
arithmetic links?
