Coherence

From Wikipedia, the free encyclopedia
(Redirected from Coherence (mathematics))

Coherence is, in general, a state or situation in which all the parts or ideas fit together well so that they form a united whole.

More specifically, coherence, coherency, or coherent may refer to the following:

Physics

[edit]
  • Coherence (physics), an ideal property of waves that enables stationary (i.e. temporally and spatially constant) interference
  • Coherence (units of measurement), a derived unit that, for a given system of quantities and for a chosen set of base units, is a product of powers of base units with no other proportionality factor than one
  • Coherence time, the time over which a propagating wave (especially a laser or maser beam) may be considered coherent; the time interval within which its phase is, on average, predictable

Mathematics

Philosophy

[edit]
  • Coherentism, philosophical theories in modern epistemology, the study of knowledge
  • Coherence theory of truth, a theory which regards truth as coherence within some specified set of sentences, propositions or beliefs
