Derived invariants from topological Hochschild homology
Benjamin Antieau, Daniel Bragg
We consider derived invariants of varieties in positive characteristic arising from topological Hochschild homology. Using theory developed by Ekedahl and Illusie-Raynaud in their…

Derived equivalences of twisted supersingular K3 surfaces
Daniel Bragg
We study the derived categories of twisted supersingular K3 surfaces. We prove a derived crystalline Torelli theorem for twisted supersingular K3 surfaces, characterizing Fourier-M…

Twistor spaces for supersingular K3 surfaces
Daniel Bragg, Max Lieblich
We develop a theory of twistor spaces for supersingular K3 surfaces, extending the analogy between supersingular K3 surfaces and complex analytic K3 surfaces. Our twistor spaces ar…
