Lighting a particular area, and falls within a given solid angle. The SI unit for luminance is candela per square metre (cd/m). The CGS unit of luminance is the stilb, which is equal to one candela per square centimetre or 10 kcd/m. The amount of useful light emitted from a source or the luminous flux is measured in lumen (lm). The SI unit of illuminance and luminous emittance, being the luminous power per area, is measured in Lux. It is used in photometry as a measure of the intensity, as perceived by the human eye, of light that hits or passes
Maximising measure under "T", i.e., for every Borel-measurable subset "A" of "X", "μ"("T"("A")) = "μ"("A"). (Note that, by the Krylov-Bogolyubov theorem, if "X" is compact and metrizable, Inv("T") is non-empty.) Define, for continuous functions "f" : "X" → R, the maximum integral function "β" by A probability measure "μ" in Inv("T") is said to be a maximising measure for "f" if Maximising measure In mathematics — specifically, in ergodic theory — a maximising measure is a particular kind of probability measure. Informally, a probability measure "μ" is a maximising measure for some function "f" if the integral of "f" with respect to
