#### Chromatic homotopy theory via spectral algebraic geometry

###### Rok Gregoric (UT Austin)

Abstract: A key aspect of chromatic homotopy theory is that structural properties of the stable homotopy category are reflected in the algebro-geometric properties of the moduli stack of formal groups. In this talk, we will discuss how to make that connection precise in the context of non-connective spectral algebraic geometry, using the stack of oriented formal groups.
