Cox ring of an algebraic stack

چکیده
We give a proper definition of the multiplicative structure following rings: Cox ring invertible sheaves on general algebraic stack; rank one reflexive normal and excellent stack. show that such rings always exist establish its (non-)uniqueness in terms an Ext-group. Moreover, we compare this with classical construction variety. Finally, application to theory Mori dream stacks.

The Cox Ring of an Algebraic Variety with Torus Action
We investigate the Cox ring of a normal complete variety X with algebraic torus action. Our first results relate the Cox ring of X to that of a maximal geometric quotient of X . As a consequence, we obtain a complete description of the Cox ring in terms of generators and relations for varieties with torus action of complexity one. Moreover, we provide a combinatorial approach to the Cox ring us...

متن کاملFiniteness theorems for the Picard objects of an algebraic stack
We prove some finiteness theorems for the Picard functor of an algebraic stack, in the spirit of SGA6, exp. XII and XIII. In particular, we give a stacky version of Raynaud’s relative representability theorem, we give sufficient conditions for the existence of the torsion component of the Picard functor, and for the finite generation of the Néron-Severi groups or of the Picard group itself. We ...
متن کاملPermutations Generated by a Depth 2 Stack and an Infinite Stack in Series are Algebraic
We prove that the class of permutations generated by passing an ordered sequence 12 . . . n through a stack of depth 2 and an infinite stack in series is in bijection with an unambiguous context-free language, where a permutation of length n is encoded by a string of length 3n. It follows that the sequence counting the number of permutations of each length has an algebraic generating function. ...
