In particular, a C k-atlas that is C 0-compatible with a C 0-atlas that defines a topological manifold is said to determine a C k differential structure on the topological manifold. The C k equivalence classes of such atlases are the distinct C k differential structures of the manifold. Each distinct differential structure is determined by a ...
Let be a function in the Lebesgue space ([,]).We say that in ([,]) is a weak derivative of if ′ = ()for all infinitely differentiable functions with () = =.. Generalizing to dimensions, if and are in the space () of locally integrable functions for some open set, and if is a multi-index, we say that is the -weak derivative of if
Most differentiable programming frameworks work by constructing a graph containing the control flow and data structures in the program. [7] Attempts generally fall into two groups: Static, compiled graph-based approaches such as TensorFlow, [note 1] Theano, and MXNet.
In mathematics, especially vector calculus and differential topology, a closed form is a differential form α whose exterior derivative is zero (dα = 0), and an exact form is a differential form, α, that is the exterior derivative of another differential form β. Thus, an exact form is in the image of d, and a closed form is in the kernel of d.
Given a smooth manifold, of dimension , and an atlas = {(,)}, then a map : is smooth on if for all there exists a chart (,), such that , and : is a smooth function from a neighborhood of () in to (all partial derivatives up to a given order are continuous).
The San Francisco 49ers suspended linebacker De’Vondre Campbell for the rest of the regular season after he refused to enter a game after losing his starting job. General manager John Lynch ...

The above characterizations can be used to determine whether or not a linear functional is a distribution, but more advanced uses of distributions and test functions (such as applications to differential equations) is limited if no topologies are placed on () and ().
