| Research Abstract |
Masaaki Ue, the representative of this research has studied 3 and 4-manifolds, in particular 4-manifolds with boundary. We show that the two invariants for 3-manifolds, which are called Fukumoto-Furuta invariant and the correction term, coincide in case of spherical 3-manifolds. These invariants are derived from the two important theories for this area of research, Seiberg-Witten theory and Heegaard Floer homology theory. Moreover we show that these invariants are represented by the previously known eta invariants. We also give explicit constraints for the structures of 4-manifolds bounded by 3-manifolds of this type in terms of the Fukumoto-Furuta invariant.
