ON EULER CHARACTERISTICS AND HIRZEBRUCH INDICES OF FOUR-DIMENSIONAL ALMOST PARA-HERMITIAN MANIFOLDS
Yasuo Matsushita (Japan)
|
Abstract: It is shown that if a compact oriented 4-manifold admits an almost para-Hermitian structure, then such a 4-manifold of some types must satisfy certain topological constraints concerning the Euler characteristic and the Hirzebruch index of the 4-manifold. |
Keywords and phrases: almost para-Hermitian structure, Euler characteristic, Hirzebruch index, Norden metric, neutral metric, 4-dimensional geometry. |
