- Title : Frobenius morphisms and derived categories on two dimensional toric
Deligne--Mumford stacks - Speaker :Ryo Okawa(RIMS) - Date & Time : 9 Nov , 2012 (Fri) 14:00~15:00 - Place : Math Science Building room 404 - Abstract : For a toric Deligne-Mumford (DM) stack over the complex number field, we can
consider a certain generalization of the Frobenius endomorphism. For such an
endomorphism of a two-dimensional toric DM stack, we show that the push-forward
of the structure sheaf generates the bounded derived category of coherent
sheaves on the stack. |
