Integral curve — In mathematics, an integral curve for a vector field defined on a manifold is a curve in the manifold whose tangent vector (i.e. time derivative) at each point along the curve is the vector field itself at that point. Intuitively, an integral… … Wikipedia

Moduli of algebraic curves — In algebraic geometry, a moduli space of (algebraic) curves is a geometric space (typically a scheme or an algebraic stack) whose points represent isomorphism classes of algebraic curves. It is thus a special case of a moduli space. Depending on… … Wikipedia
Differential geometry of curves — This article considers only curves in Euclidean space. Most of the notions presented here have analogues for curves in Riemannian and pseudo Riemannian manifolds. For a discussion of curves in an arbitrary topological space, see the main article… … Wikipedia

Exponential integral — is a mathematical function of a single argument which has no established notation.DefinitionsFor real values of x , the exponential integral Ei( x ) can be defined as : mbox{Ei}(x)=int { infty}^xfrac{e^t}t,dt., The definition above can be used… … Wikipedia
Fresnel integral — S(x) and C(x) The maximum of C(x) is about 0.977451424. If πt²/2 were used instead of t², then the image would be scaled vertically and horizontally (see below). Fresnel integrals, S(x) and C(x), are two transcendental functions named aft … Wikipedia
Path integral — may refer to: * Line integral, the integral of a function along a curve * Functional integration, the integral of a functional over a space of curves * Path integral formulation of quantum mechanics using functional integration, due to Richard… … Wikipedia
Born coordinates — / ) are time like curves with fixed R .In relativistic physics, the Born coordinate chart is a coordinate chart for (part of) Minkowski spacetime, the flat spacetime of special relativity. It is often used to analyze the physical experience of… … Wikipedia
Congruence (manifolds) — In the theory of smooth manifolds, a congruence is the set of integral curves defined by a nonvanishing vector field defined on the manifold. Congruences are an important concept in general relativity, and are also important in parts of… … Wikipedia
Method of characteristics — In mathematics, the method of characteristics is a technique for solving partial differential equations. Typically, it applies to first order equations, although more generally the method of characteristics is valid for any hyperbolic partial… … Wikipedia
