Let a normal vector be defined along a closed curve on the surfaces.
We define the closed curve on the torus using 4 π- periodic vector-function ρ ρv.
A closed geodesic on a Riemannian manifold is a closed curve that is also geodesic.
The closed curve representing the successive stress-strain status of the material during a cyclic deformation.
A meander or closed meander is a self-avoiding closed curve which intersects a line a number of times.
The surface is called a one-sided surface if the tangent space local orientation changes sign along a closed curve on a surface.
This formula defines a closed curve contained in the rectangle-a≤ x≤+a and-b≤ y≤+b.
When 0< e<1 the original curve is an ellipse and the inverse is a simple closed curve with an acnode at the origin.
The isoperimetric inequality: among closed curves with a given perimeter, the circle gives the unique maximum area.
With the help of a computer mathematics system we calculate normal curvature indicatrixes for examined surfaces along the defined closed curve.
If two disjoint simple smooth closed curves evolve, they remain disjoint until one of them collapses to a point.
Any finite graph has a finite(though perhaps exponential)number of distinct simple cycles, and if the graph is embedded into three-dimensional space then each of these cycles forms a simple closed curve.
Dance of death of shadows passing makes the circle on the closed curve limited by the dense sphere, and the exit isn't present from it.
For a given closed curve, the isoperimetric quotient is defined as the ratio of its area and that of the circle having the same perimeter.
An elegant direct proof based on comparison of a smooth simple closed curve with an appropriate circle was given by E. Schmidt in 1938.
We define a closed curve s s(v) and the normal vector n n(v) that goes along the curve s and returns to the starting point with an opposite direction.
These can be defined most simply in the projective plane as simple closed curves any two of which meet in a single crossing point.
In mathematics, the winding number of a closed curve in the plane around a given point is an integer representing the total number of times that curve travels counterclockwise around the point.
This theorem is analogous to the four-vertex theorem,that every smooth simple closed curve in the plane has four vertices extreme points of curvature.
However, in finite projective geometry, ovals are instead defined as sets for which each point has a unique line disjoint from the rest of the set,a property that in Euclidean geometry is true of the smooth strictly convex closed curves.
Suppose that c is a simple closed curve in a closed, orientable surface S. Let A be a tubular neighborhood of c.
This question can be shown to be equivalent to the following problem: Among all closed curves in the plane enclosing a fixed area, which curve(if any) minimizes the perimeter?
Any closed curve within the plane bounds a disk below the plane that does not pass through any other graph feature, and any closed curve through the apex bounds a disk above the plane that does not pass through any other graph feature.
Given a fixed oriented line L in the Euclidean plane R2, a meander of order n is a non-self-intersecting closed curve in R2 which transversally intersects the line at 2n points for some positive integer n.

The linking number of two closed curves in three-dimensional space is a topological invariant of the curves: it is a number, defined from the curves in any of several equivalent ways, that does not change if the curves are moved continuously without passing through each other.
The problem can be stated as follows: Among all closed curves in the plane of fixed perimeter, which curve(if any) maximizes the area of its enclosed region?
