  2. Propagation constant - Wikipedia

    en.wikipedia.org/wiki/Propagation_constant

    α, the real part, is called the attenuation constant; β, the imaginary part, is called the phase constant ; more often j is used for electrical circuits. That β does indeed represent phase can be seen from Euler's formula:

  4. Dispersion relation - Wikipedia

    en.wikipedia.org/wiki/Dispersion_relation

    As mentioned above, when the focus in a medium is on refraction rather than absorption—that is, on the real part of the refractive index—it is common to refer to the functional dependence of angular frequency on wavenumber as the dispersion relation. For particles, this translates to a knowledge of energy as a function of momentum.

  7. Multipartite graph - Wikipedia

    en.wikipedia.org/wiki/Multipartite_graph

    In graph theory, a part of mathematics, a k-partite graph is a graph whose vertices are (or can be) partitioned into k different independent sets. Equivalently, it is a graph that can be colored with k colors, so that no two endpoints of an edge have the same color. When k = 2 these are the bipartite graphs, and when k = 3 they are called the ...

  8. Tuple-generating dependency - Wikipedia

    en.wikipedia.org/wiki/Tuple-generating_dependency

    In relational database theory, a tuple-generating dependency (TGD) is a certain kind of constraint on a relational database. It is a subclass of the class of embedded dependencies (EDs). An algorithm known as the chase takes as input an instance that may or may not satisfy a set of TGDs (or more generally EDs) and, if it terminates (which is a ...
