Transversality problems in string topology and de Rham chains (JAPANESE)
[ Abstract ]
The starting point of string topology is the work of Chas-Sullivan, which uncovered the Batalin-Vilkovisky(BV) structure on homology of the free loop space of a manifold.
It is important to define chain level structures beneath the BV structure on homology, however this problem is yet to be settled.
One of difficulties is that, to define intersection products on chain level, we have to address the transversality issue.
In this talk, we introduce a notion of "de Rham chain" to bypass this trouble, and partially realize expected chain level structures.
