Another example is the application of conformal mapping technique for solving the boundary value problem of liquid sloshing in tanks. [ 19 ] If a function is harmonic (that is, it satisfies Laplace's equation ∇ 2 f = 0 {\displaystyle \nabla ^{2}f=0} ) over a plane domain (which is two-dimensional), and is transformed via a conformal map to ...
In complex analysis, a Schwarz–Christoffel mapping is a conformal map of the upper half-plane or the complex unit disk onto the interior of a simple polygon. Such a map is guaranteed to exist by the Riemann mapping theorem (stated by Bernhard Riemann in 1851); the Schwarz–Christoffel formula provides an explicit construction.
In conformal geometry, a conformal Killing vector field on a manifold of dimension n with (pseudo) Riemannian metric (also called a conformal Killing vector, CKV, or conformal colineation), is a vector field whose (locally defined) flow defines conformal transformations, that is, preserve up to scale and preserve the conformal structure.
Points in e 123 map onto the null cone—the null parabola if we set =. We can consider the locus of points in e 123 s.t. in conformal space g ( x ) ⋅ A = 0 {\displaystyle g(\mathbf {x} )\cdot A=0} , for various types of geometrical object A.
Example of a Joukowsky transform. The circle above is transformed into the Joukowsky airfoil below. In applied mathematics , the Joukowsky transform (sometimes transliterated Joukovsky , Joukowski or Zhukovsky ) is a conformal map historically used to understand some principles of airfoil design.
A rectangular grid (top) and its image under a conformal map f (bottom). It is seen that f maps pairs of lines intersecting at 90° to pairs of curves still intersecting at 90°. A conformal map is a function which preserves angles locally. In the most common case the function has a domain and range in the complex plane. More formally, a map,
Conformal Ward identities are linear equations that correlation functions obey as a consequence of conformal symmetry. [4] They can be derived by studying correlation functions that involve insertions of the energy–momentum tensor. Their solutions are conformal blocks. For example, consider conformal Ward identities on the sphere.
In mathematics, Carathéodory's theorem is a theorem in complex analysis, named after Constantin Carathéodory, which extends the Riemann mapping theorem.The theorem, published by Carathéodory in 1913, states that any conformal mapping sending the unit disk to some region in the complex plane bounded by a Jordan curve extends continuously to a homeomorphism from the unit circle onto the ...
