Splicing and the SL(2,C) Casson invariant

Hans U. Boden, Cynthia L. Curtis

Published 2007-07-27Version 1

We establish a formula for the SL(2,C) Casson invariant of spliced sums of homology spheres along knots. Along the way, we show that the SL(2,C) Casson invariant vanishes for spliced sums along knots in the 3-sphere.
