# K3 spectra

@article{Szymik2010K3S, title={K3 spectra}, author={Markus Szymik}, journal={Bulletin of the London Mathematical Society}, year={2010}, volume={42} }

The notion of a K3 spectrum is introduced in analogy with that of an elliptic spectrum and it is shown that there are ‘enough’ K3 spectra in the sense that for all K3 surfaces X in a suitable moduli stack of K3 surfaces there is a K3 spectrum whose underlying ring is isomorphic to the local ring of the moduli stack in X with respect to the etale topology, and similarly for the ring of formal functions on the formal deformation space.

Abstract.In this paper we give a characterization of the height of K3 surfaces in characteristic p>0. This enables us to calculate the cycle classes in families of K3 surfaces of the loci where the…

In this note we define moduli functors of (primitively) polarized K3 spaces. We show that they are representable by Deligne-Mumford stacks over Spec(Z). Further, we look at K3 spaces with a level…

Moduli spaces of varieties in characteristic p are stratified by Newton polygons. For example, the moduli space of polarized K3 surfaces of degreedadmits a stratification by the height h. Using the…

We use bordism theory to construct periodic cohomology theories, which we call elliptic cohomology, for which the cohomology of a point is a ring of modular functions. These are complex-oriented…
