Non-isotopic Legendrian Submanifolds in $\R^{2n+1}$
Joint work with Tobias Ekholm and Michael G. Sullivan,
Preprint 2002

The contact homology, rigorously defined in The Contact Homology of Legendrian Submanifolds in $\R^{(2n+1)}$, is computed for a number of Legendrian submanifolds in standard contact $(2n+1)$-space. The homology is used to detect infinite families of pairwise non-isotopic Legendrian n-spheres, n-tori, and surfaces which are indistinguishable using previously known invariants.
