Secondary title: | Hairy ball theorem |
Secondary abstract: | In this thesis we show some facts about existence of a non vanishing continuous tangent vector field on a $n$-dimensional sphere. At first we explicitly construct such vector field or we indicate the non existence of such vector field at low dimensions and then we generalize the idea to higher dimensions. In the two-dimensional case we also examine other objects and point out the indicator that sets the number of isolated points at which the vector field vanishes. As a consequence of our main theorem we also prove the Brower fixed-point theorem. |
