第五周:测地线;Exponential maps;同伦;管状邻域;拓扑度;拓扑度的同伦的不变性;如果值域是维球面上述命题可逆;代数基本定理;index of singularity of a vector field;index of a hyperbolic singularity;欧拉特征;Hairy ball theorem;相交数;
第六周:Morse Theory;The Morse Lemma;gradient field;Quadratic forms,Chain complex;Singular complex;Singular homology;Relative homology;exact sequence;snake lemma;diagram chasing;prism operator,barycentric subdivision,Meyer-Vietoris sequence,five lemma,excision theorem,Morse inequalities;CW-complex;Cellular homology
第七周:differential forms;exterior derivative;the stokes theorem;the de Rham cohomology;poincaré lemma;The cohomology group of ;Poincaré duality,The de Rham theorem,
