讲座提要:

A manifold which is like a projective plane is a simply-connected closed smooth manifold whose homology equals three copies of Z. In this talk I will discuss our computation of the mapping class group of these manifolds, as well as some applications in geometry. This is a joint work with WANG Wei from Shanghai Ocean University.

    AbstractZ2 harmonic 1-forms was introduced by Taubes as the boundary appearing in the compactification of the moduli space of flat SL(2,C) connections. Although from gauge theory aspect, Z2 harmonic 1-forms should exist widely, it is highly challenging to explicitly construct examples of them. Besides the curvature condition, there seems to have more obstruction to the existence of Z2 harmonic ...

    AbstractThe original version of Sullivan's rational surgery realization theorem provides necessary and sufficient conditions for a prescribed rational cohomology ring to be realized by a simply-connected smooth closed manifold. We will present a version of the theorem for almost complex manifolds. It has been shown there exist closed smooth manifolds M^n of Betti number b_i=0 except b_0=b_{n/2}...
