Editing Conjugation (section)

==Mathematics==
*[[Complex conjugation]], the change of sign of the imaginary part of a complex number
*[[Conjugate (square roots)]], the change of sign of a square root in an expression
*[[Conjugate element (field theory)]], a generalization of the preceding conjugations to roots of a polynomial of any degree 
*[[Conjugate transpose]], the complex conjugate of the transpose of a matrix
*[[Harmonic conjugate]] in complex analysis
*[[Conjugate (graph theory)]], an alternative term for a line graph, i.e. a graph representing the edge adjacencies of another graph
*In group theory, various notions are called conjugation: 
**[[Inner automorphism]], a type of conjugation homomorphism
**[[Conjugacy class]] in group theory, related to matrix similarity in linear algebra
**[[Conjugation (group theory)]], the image of an element under the conjugation homomorphisms
**[[Conjugate closure]], the image of a subgroup under the conjugation homomorphisms
*[[Free monoid#Conjugate words|Conjugate words]] in combinatorics; this operation on strings resembles conjugation in groups
*[[Isogonal conjugate]], in geometry
*[[Conjugate gradient method]], an algorithm for the numerical solution of particular systems of linear equations
*[[Conjugate points]], in differential geometry
*[[Topological conjugation]], which identifies equivalent dynamical systems
*[[Convex conjugate]], the ("dual") lower-semicontinuous convex function resulting from the Legendre–Fenchel transformation of a "primal" function
