If you have a question about this talk, please contact info@newton.ac.uk. HHHW03 - Derived algebraic geometry and chromatic homotopy theory It is a classical problem in algebraic geometry to decide whether a class in the singular cohomology of a smooth complex variety X is algebraic, that is if it can be realized as the fundamental class of an algebraic subvariety of X. One can ask a similar question for motivic spectra: Given a motivic spectrum E, which classes in the topological E-cohomology of X come from motivic classes. I would like to discuss this question and examples of non-algebraic classes for the tower of Brown-Peterson spectra.
