{wiki=Orientation_sheaf}
In algebraic geometry and related fields, an **orientation sheaf** is a concept that arises in the context of differentiable manifolds and schemes. It provides a way to systematically keep track of the "orientation" of a geometrical object, which is vital in various mathematical and physical applications, such as integration, intersection theory, and the study of moduli spaces.
