SoSe 24 Oberseminar: Motivic spectra

Time and place: Tuesday 14:14-15:45 in M311 and online

In this seminar, we will present the recent theory of motivic spectra without A¹-invariance. We will prove the universal property of the algebraic K-theory of derived schemes due to Annala and Iwasa; develop the theory of oriented motivic spectra and construct algebraic cobordism as the universal oriented theory; explain the formalism of motivic filtrations giving rise to prismatic, syntomic, and motivic cohomology; prove Poincaré duality and explore applications of the latter, such as the Landweber exact functor theorem and the construction of the category of (non-A¹-invariant) motives with rational coefficients over any derived scheme.
