Spin c -structures and Dirac operators on contact manifolds

Any contact metric manifold has a Spin c -structure. Thus, we study on any Spin c -spinor bundle of a contact metric manifold, Dirac type operators associated to the generalized Tanaka–Webster connection. Bochner–Lichnerowicz type formulas are derived in this setting and vanishing theorems are obtai...

Popis
Shrnutí:Any contact metric manifold has a Spin c -structure. Thus, we study on any Spin c -spinor bundle of a contact metric manifold, Dirac type operators associated to the generalized Tanaka–Webster connection. Bochner–Lichnerowicz type formulas are derived in this setting and vanishing theorems are obtained.
