Mondays, 16.00-17.30, room WI 401, begin: 29 January
The notion of
The foundational examples for applications of Gromov's ideas include (i) Hirsch-Smale immersion theory, (ii) Nash-Kuiper C 1-isometric immersion theory, (iii) existence of symplectic and contact structures on open manifolds.
Gromov has developed several powerful methods to prove h-principles. In this seminar we want to discuss two of these: the covering homotopy method and convex integration theory.
Students receive credit (7 stp.) for giving one of the 90 min. presentations. The first four lectures (after the introductory survey) require as background knowledge only a first course in manifold theory. Please contact H.Geiges if you are interested in participating actively.
Main source for this seminar will be the book Embeddings and Immersions by M.Adachi (on order).
N.B.The previously announced seminar on geometries of surfaces and 3-manifolds will not take place.
