Using a new definition of the second and third Johsnon homomorphisms, we simplify and
extend the work of Morita on the Casson invariant of homology-spheres defined by Heegard
splittings. In particular, we calculate the Casson invariant of the homology-sphere
obtained by gluing two handlebodies along a homeomorphism of the boundary belonging to
the Torelli subgroup.
We discuss polynomial representations for 2-bridge knots and determine the minimal degree sequence for all such knots. We apply the connection between rational tangles and 2-bridge knots.
