Title: Motivic Donaldson Thomas invariants and the Kontsevich Soibelman integration map (Part II)
Date (JST): Mon, Jan 30, 2012, 15:30 - 17:00
Place: Seminar Room B
Abstract: In the second part of the talk I will discuss technical aspects of the integration map, especially the ingredients that are required for the map to have the key property that it takes the Hall algebra product to Looijenga's product of equivariant motives. In practice it is this property that is needed to simplify computations of motivic generating series. This will involve a discussion of the concept of orientation data, which I will give a full account of.
