Universal cohomology theories

Vortrag von Prof. Dr. Luca Barbieri Viale

In this talk I shall explain the theoretical approach to motives following Nori's original idea. Motivic categories are associated with cohomology theories on a suitable base category, e.g. this applies to the construction of abelian categories of log motives and motives with coefficients. The tensor structure is induced by the cartesian tensor structure on the base category via cohomological Künneth formulas (as explained in recent papers with A. Huber & M. Prest)
