Just as there are various types of manifolds, there are various types of maps of manifolds. PDIFF serves to relate DIFF and PL, and it is equivalent to PL.. In geometric topology, the basic types of maps correspond to various categories of manifolds: DIFF for smooth functions between differentiable manifolds, PL for piecewise linear functions between piecewise linear manifolds, and TOP for ...
A smooth curve that is not closed is often referred to as a smooth arc. [6] The parametrization of a curve provides a natural ordering of points on the curve: () comes before () if <. This leads to the notion of a directed smooth curve. It is most useful to consider curves independent of the specific parametrization.
SketchUp is a 3D modeling software that is used to create and manipulate 3D models. It is used in architecture and interior design.. SketchUp is owned by Trimble Inc. The software has a free web-based version, and three paid subscriptions to gain access to applications for Windows and macOS.
Consider the standard CW-decomposition of the n-sphere, with one zero cell and a single n-cell.From the point of view of smooth manifolds, this is a degenerate decomposition of the sphere, as there is no natural way to see the smooth structure of from the eyes of this decomposition—in particular the smooth structure near the 0-cell depends on the behavior of the characteristic map : in a ...

Some retailers are using President-elect Donald Trump's proposed tariffs to urge consumers to shop now, suggesting if the import duties go into effect next year, a range of goods could cost ...
Common smooth functors include, for some vector space W: [2] F(W) = ⊗ n W, the nth iterated tensor product; F(W) = Λ n (W), the nth exterior power; and F(W) = Sym n (W), the nth symmetric power. Smooth functors are significant because any smooth functor can be applied fiberwise to a differentiable vector bundle on a manifold.
