Heegaard genus and rank of link complements
 
 
Description:  In this talk we will discuss the relationship between the Heegaard genus and rank of 3-dimentional manifolds. Despite some recent advances in this topic, little is known for manifolds arising as link complements in S^3. We will provide a very rich class of link complements for which rank equals Heegaard genus. This is achieved by computing the tunnel number of these links. We then discuss some recent work joint with J. Nogueira, A. Salgueiro and other people, where we attempt to estimate tunnel number based on combinatorial information arising from a diagram.
