  2. Topological conjugacy - Wikipedia

    en.wikipedia.org/wiki/Topological_conjugacy

    In mathematics, two functions are said to be topologically conjugate if there exists a homeomorphism that will conjugate the one into the other. Topological conjugacy, and related-but-distinct § Topological equivalence of flows, are important in the study of iterated functions and more generally dynamical systems, since, if the dynamics of one iterative function can be determined, then that ...

  3. Conjugated system - Wikipedia

    en.wikipedia.org/wiki/Conjugated_system

    Cinnamaldehyde is a naturally-occurring compound that has a conjugated system penta-1,3-diene is a molecule with a conjugated system Diazomethane conjugated pi-system. In theoretical chemistry, a conjugated system is a system of connected p-orbitals with delocalized electrons in a molecule, which in general lowers the overall energy of the molecule and increases stability.

  4. Conjugacy problem - Wikipedia

    en.wikipedia.org/wiki/Conjugacy_problem

    In abstract algebra, the conjugacy problem for a group G with a given presentation is the decision problem of determining, given two words x and y in G, whether or not they represent conjugate elements of G. That is, the problem is to determine whether there exists an element z of G such that =.

    Conjugate (acid-base theory), a system describing a conjugate acid-base pair; Conjugated system, a system of atoms covalently bonded with alternating single and multiple bonds; Conjugate variables (thermodynamics), pairs of variables that always change simultaneously; Conjugate quantities, observables that are linked by the Heisenberg ...

  6. Conjugacy class - Wikipedia

    en.wikipedia.org/wiki/Conjugacy_class

    In mathematics, especially group theory, two elements and of a group are conjugate if there is an element in the group such that =. This is an equivalence relation whose equivalence classes are called conjugacy classes .

  7. Conjugate variables - Wikipedia

    en.wikipedia.org/wiki/Conjugate_variables

    Conjugate variables are pairs of variables mathematically defined in such a way that they become Fourier transform duals, [1] [2] or more generally are related through Pontryagin duality. The duality relations lead naturally to an uncertainty relation—in physics called the Heisenberg uncertainty principle —between them.
