Abstract

Let M be a smooth connected Hausdorff manifold of dimension n. We denote by TpM the tangent space of M, in p of M, by tauM the fibre bundle of M and by TM , the total space of such fibre bundle. A vector field is a continuous map M to TpM which associates to each point p of M, a vector v(p) in TpM. Then a vector field is a section v : M to TpM. Sankaran presents a very interesting survey on the vector field problem, more specifically on homogeneous spaces. This problem consists on the determination of the maximum number, called span of M, such that there exist vector fields v1, v2, · · · , vr in M such that v1(p), v2(p), · · · , vr(p) in TpM are linearly independent for all p in M. The objective of this project is to study this case to obtain a generalization for other types of spaces. The student intends to do an internship at University of Warmia and Mazury in Poland, under the supervision of Marek Golasinsiki from 2021 January until March.
