In summary, the term 'Cn-close' refers to the C^n topology, specifically the Whitney topology. This means that two curves are considered C^1-close if they satisfy certain conditions involving their derivatives. A reference for this is the book Differential Topology by M Hirsch.

I'm reading a paper and have came across the term 'Cn-close' in the sense of a curve being C1-close to a circle for example, but can't find a definition of this term anywhere, and would be grateful if anyone could help.

This is a reference to the C^n topology, or Whitney topology: http://en.wikipedia.org/wiki/Whitney_topologies

In your case, to say that " As soon as two curves c1, c2: [0,1] --> R² are C^1-close together, then "blahblah"" means that there exists epsilon >0 such that whenever |c1(t) - c2(t)| < epsilon and |dc1/dt - dc1/dt| < epsilon for all t, then "blah blah" holds.

A reference is Differential Topology by M Hirsch.
 

FAQ: What is the Definition of C1-Close Curve in Whitney Topology?

What is a C1-Close Curve?

A C1-close curve is a type of mathematical curve that is smooth and continuous, meaning it has no sharp corners or breaks. It is also referred to as a C1 curve, where the "C" stands for continuous and the "1" represents the first derivative of the curve, which is also continuous.

How is a C1-Close Curve different from other types of curves?

C1-close curves are different from other types of curves, such as C0 or C2 curves, because they have a continuous first derivative. This means that the slope of the curve is also continuous, resulting in a smoother and more visually appealing curve.

What are some real-world examples of C1-Close Curves?

C1-close curves can be seen in various natural and man-made objects, such as roads, rivers, and bridges. They can also be found in the shapes of certain fruits, like bananas and avocados, as well as in the curves of human body parts, like arms and legs.

How are C1-Close Curves used in scientific research?

C1-close curves are commonly used in fields such as mathematics, physics, and engineering to model and analyze real-world phenomena. They are also used in computer graphics and animation to create smooth and realistic curves for 3D objects.

Are C1-Close Curves always perfect and smooth?

No, C1-close curves may not always be perfect and smooth. They can have imperfections, such as slight bumps or dips, due to limitations in the data or methods used to create the curve. However, they are generally smoother and more continuous compared to other types of curves.
