neutral almost Kähler manifold deformation of G structure Department of Complex Analysis
Institute of Mathematics and Informatics at the Bulgarian Academy of Sciences
Common deformations for neutral pseudoriemann manifolds with compatible almost complex structure and closed fundamental two-form are considered. An example of nontrivial common deformation on the cylindrical Heisenberg group with invariant almost complex structure and neutral pseudometric is given. 2000 AMS Subject Classificalion: 53C15.
