Principal fibre bundles with the $1$-dimensional toroidal group
In this paper, we study the principal fibre bundles whose structure group is the 1-dimensional toroidal group T 1 , mainly from the differential* geometrical point of view.Therefore all the spaces considered here are differentiable manifolds (of class C°°) with the second countability axiom and all the maps are supposed …
