Cohomological boundedness of twisted coherent Springer sheaves

Oron Y. Propp

We prove that the coherent Springer sheaf and its parabolic analogues are concentrated in cohomological degree $0$ , as predicted by Ben-Zvi-Chen-Helm-Nadler, Zhu, Emerton-Gee-Hellm…

Constructing explicit K3 spectra

Oron Y. Propp

Following an overview of the relevant theory, we construct several explicit examples of height-3 K3 spectra.

Cartan images and $ℓ$ -torsion points of elliptic curves with rational $j$ -invariant

Oron Y. Propp

Let $ℓ$ be an odd prime and $d$ a positive integer. We determine when there exists a degree- $d$ number field $K$ and an elliptic curve $E / K$ with $j(E)\in\mathbb{Q}\setminus\{0,…
