Sometimes, it can be useful to use an alternative approach to endow a manifold with a ''Ck''-structure. Here ''k'' = 1, 2, ..., ∞, or ω for real analytic manifolds. Instead of considering coordinate charts, it is possible to start with functions defined on the manifold itself. The structure sheaf of ''M'', denoted C''k'', is a sort of functor that defines, for each open set ''U'' ⊂ ''M'', an algebra C''k''(''U'') of continuous functions ''U'' → R.
