The field of moduli K of a curve X a priori defined over the separable closure K s of K need not be a field of definition. This paper shows that the obstruction is essentially the same as the obstruction to K being a field of definition of the cover X ~ X/Aut(X). Using previous results of Dbbes-Doua
A basic system k a nonempty collection of finite incomparable subsets of a set such that for any two subsets or bases in the collection, any flement of one basis can be replaced by some element of the other to give another basis in the collection. In a basic system, any subset of one basis can be bi
