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. The rst part is centered around a certain topology on a bred category over a site. In mathematics a stack or 2-sheaf is, roughly speaking, a sheaf that takes values in categories rather than sets. .
