I just want to know how we can define a sections of a tensor product of two vector bundles .

comment Projectively equivalent connections
Thanks Vladimir . yes , you are right. 1-form doesn't need to be closed. could you please tell me where I can study more about this?

comment projective plane and tetrahedra
is it correct to say that we are using the ' principle of duality ' here ?

comment projective plane and tetrahedra
suppose we have the point [1,0,0,0] in RP3 and the lines going through this point . I just can't see why this collection form a projective plane.

comment projective triangulation and holonomy map
What do we have to prove if we want to say that a topologically triangulated manifold M admits a real projective structure such that the topological triangulations is a projective one?

comment complement of a codimension-one projective subspace
in your article " geometric structures on low-dimensional manifolds " section - 1. theorem - 3 , I really don't understand it. why we need to show that around the edges the identifications give us trivial holonomy elements? and why you said " at each sphere the triangulations are from points of RP2 " ? and then you concluded that " at each sphere and the vertex on it , the holonomy around the vertex is the identity map " ??
