...n of Φ [22]. One can actually show that the first condition in (A.3) implies the other ones [7, Section 6.1] (see also [22]). An almost contact structure (Φ,ξ,η) such that NΦ +dη⊗ξ= 0 is called normal [7]. So normal almost contact structures provide examples of complex structures on the Atiyah algebroid (of the trivial line bundle), and, in turn, of generalized contact structures of complex type. It t...

... contact structure on a manifold M is a triple (Φ,ξ,η), where Φ : TM→TM is a (1,1)-tensor, ξis a vector field, and ηis a 1-form on Msuch that Φ2 = −id +η⊗ξ, Φ(ξ) = 0, η◦Φ = 0, and η(ξ) = 1. See, e.g., [7] for more details. The idea behind this definition is that an almost contact structure is the odd-dimensional analogue of an almost complex structure. We believe that THE LOCAL STRUCTURE OF GENERALIZED...

...treme they encompass line bundles equipped with an integrable complex structure on their gauge algebroid. In turn, such line bundles are intrinsic models for so called normal almost contact manifolds [7]. In our opinion, generalized contact bundles have an advantage over previous proposals of a generalized contact geometry: they have a firm conceptual basis in the so called homogenization scheme [40],...
