Reduction of sasakian manifolds

Domenii publicaţii > Matematica + Tipuri publicaţii > Articol în revistã ştiinţificã

Autori: G. Grantcharov, L. Ornea

Editorial: J. Math. Physics, 42, p.3809-3816, 2001.

Rezumat:

We extend the contact reduction to sasakian manifolds.
We relate this reduction with the Kaehler one. We
find sufficient conditions for the reduced space to be Einstein.
We provide explicit examples of S^1 reduction of odd
standard spheres.
