Frobenius push-forwards
Freitag, 19.11.10, 11:15-12:15, Raum 127, Eckerstr. 1
If \(X\) is a scheme of characteristic \(p>0\), we have the absolute\nFrobenius morphism \(F: X\to X\). For any coherent sheaf \(\mathcal{F}\) on \(X\)\nwe can then try to understand the sheaf \(F_* \mathcal{F}\) (the easiest example,\n\(F_* \mathcal{O}\) on \(\mathbb{P}1\), is already nontrivial).\nI will provide state-of-the-art results concerning these Frobenius\npush-forwards\non several classes of varieties and show their important applications.\nThe second part of the talk will be devoted to the case when \(X\) is\na smooth quadric hypersurface in \(\mathbb{P}^n\).\n
