  • langmuir isotherm — A Langmuir isotherm is a classical relationship between the concentrations of a solid and a fluid, used to describe a state of no change in the sorption process.
  • laplace transform — a map of a function, as a signal, defined especially for positive real values, as time greater than zero, into another domain where the function is represented as a sum of exponentials.
  • larmor precession — the precession of charged particles, as electrons, placed in a magnetic field, the frequency of the precession (Larmor frequency) being equal to the electronic charge times the strength of the magnetic field divided by 4π times the mass.
  • laryngopharyngeal — of, relating to, or involving the larynx and pharynx.
  • laurent's theorem — the theorem that a function that is analytic on an annulus can be represented by a Laurent series on the annulus.
  • law of reflection — the principle that when a ray of light, radar pulse, or the like, is reflected from a smooth surface the angle of reflection is equal to the angle of incidence, and the incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane.
  • law of refraction — the principle that for a ray, radar pulse, or the like, that is incident on the interface of two media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocity of the ray in the first medium to the velocity in the second medium and the incident ray, refracted ray, and normal to the surface at the point of incidence all lie in the same plane.
  • law of the jungle — a system or mode of action in which the strongest survive, presumably as animals in nature or as human beings whose activity is not regulated by the laws or ethics of civilization.

  • least fixed point — (mathematics)   A function f may have many fixed points (x such that f x = x). For example, any value is a fixed point of the identity function, (\ x . x). If f is recursive, we can represent it as f = fix F where F is some higher-order function and fix F = F (fix F). The standard denotational semantics of f is then given by the least fixed point of F. This is the least upper bound of the infinite sequence (the ascending Kleene chain) obtained by repeatedly applying F to the totally undefined value, bottom. I.e. fix F = LUB {bottom, F bottom, F (F bottom), ...}. The least fixed point is guaranteed to exist for a continuous function over a cpo.
  • least upper bound — an upper bound that is less than or equal to all the upper bounds of a particular set. 3 is the least upper bound of the set consisting of 1, 2, 3. Abbr.: lub.
