In this Section we will present the construction of a model category of D-stacks.It will be our derived version of the category of stacks that is commonly used in moduli theory, and all our examples of derived moduli stacks will be objects of this category. To every discrete group G we assign the basic groupoid BG = pt=G as follows: An object of the category BG is a G-torsor T and morphisms in this category are morphisms of G-sets. Here it is.

A stack A A is called a moduli stack for certain structures, if for any other object X X the groupoid of morphisms X â A X \to A into A A is equivalent to the groupoid of these kinds of structures on X X.. Effect stacking occurs when a single effect is applied more than once to a target. It is also often used more restrictively as a synonym for (2,1)-sheaf. In this paper, we prove that there exists an equivalence between 2-category of smooth Deligne-Mumford stacks with torus-embeddings and actions, and the 1-category of stacky fans.

I learned that a stack is a contravariant functor$\mathcal{F}:\mathcal{C}^{\operatorname{op}}\to\mathbf{Grpd}$satisfying a descent property and, categories fibered in groupoids over$\mathcal{C}$is an intuitive way to think about stacks, where$\mathcal{C}$is a site (category equipped with a coverage).
