| Aims |
|
The main purpose of this course consists in presentation of the basic problems of Differential Topology. Some important results concerning the smooth manifolds and smooth mapping as well some applications are given. Some results obtained by Chair of Geometry in the study of critical points of mappings beetwen differentiable manifolds are included in chapter 3. |

smooth mappings (smooth partition of unity). Differentiable submanifolds. Manifolds with boundary. Homotopy and isotopy of smooth mappings. The modulo 2 degree and some applications. 2. Fundamental results in Differential topolgy. Sets of zero measure on a manifold. Sard'theorem and applications. Whitney'embeding theorem. 3.
