%0 Journal Article %T The curvature tensor of almost cosymplectic and almost Kenmotsu (¦Ê,¦Ì,¦Í)-spaces %A Alfonso Carriazo %A Ver¨®nica Mart¨ªn-Molina %J Mathematics %D 2012 %I arXiv %R 10.1007/s00009-013-0246-4 %X We study the Riemann curvature tensor of (\kappa,\mu,\nu)-spaces when they have almost cosymplectic and almost Kenmotsu structures, giving its writing explicitly. This leads to the definition and study of a natural generalisation of the contact metric (\kappa,\mu,\nu)-spaces. We present examples or obstruction results of these spaces in all possible cases. %U http://arxiv.org/abs/1201.5565v2
