The Atiyah-Singer Index Formula for Subelliptic Operators on Contact Manifolds, Part II
We present a new solution to the index problem for hypoelliptic operators in the Heisenberg calculus on contact manifolds, by constructing the appropriate topological K-theory cocycle for such operators. Its Chern character gives a cohomology class to which the Atiyah-Singer index formula can be applied. Such a K-cocycle has already been constructed by Boutet de Monvel for Toeplitz operators, a...
متن کاملThe Atiyah-Singer Index Formula for Subelliptic Operators on Contact Manifolds, Part I
The Atiyah-Singer index theorem gives a topological formula for the index of an elliptic differential operator. The topological index depends on a cohomology class that is constructed from the principal symbol of the operator. On contact manifolds, the important Fredholm operators are not elliptic, but hypoelliptic. Their symbolic calculus is noncommutative, and is closely related to analysis o...

متن کاملNotes on the Atiyah-Singer Index Theorem
This is arguably one of the deepest and most beautiful results in modern geometry, and in my view is a must know for any geometer/topologist. It has to do with elliptic partial differential operators on a compact manifold, namely those operators P with the property that dim ker P, dim coker P < ∞. In general these integers are very difficult to compute without some very precise information abou...
متن کاملSubelliptic SpinC Dirac operators, III The Atiyah-Weinstein conjecture
In this paper we extend the results obtained in [9, 10] to manifolds with SpinC-structures defined, near the boundary, by an almost complex structure. We show that on such a manifold with a strictly pseudoconvex boundary, there are modified ∂̄-Neumann boundary conditions defined by projection operators, Reo + , which give subelliptic Fredholm problems for the SpinC-Dirac operator, ð eo + . We in...
