The Lagrangian filtration of the mapping class group and finite-type invariants of homology spheres
Jerome Levine
In a recent paper we defined a new filtration of the mapping class group--the "Lagrangian" filtration. We here determine the successive quotients of this filtration, up to finite i…

Concordance of boundary links
Jerome Levine
We show that the twisted signature invariants of boundary link concordance derived from unitary representations of the free group are actually ordinary link concordance invariants.…
