On the AC-contact Bochner curvature tensor field on almost cosymplectic manifoldsHiroshi EndoKohnodai Senior High School, 2-4-1, Kohnodai, Ichikawa-Shi 272, Chiba-Ken, JapanAbstract: On an almost cosymplectic manifold we define a new modified contact Bochner curvature tensor field which is invariant with respect to $D$-homothetic deformation. Then we generalize a theorem of Olszak [5] and describe some manifolds with vanishing its new modified contact Bochner curvature tensor field. Keywords: almost cosymplectic manifold, cosymplectic manifold, $D$-homothetic deformation Classification (MSC2000): 53C15, 53C25 Full text of the article:
