In mathematics , the Kantorovich inequality is a particular case of the Cauchy–Schwarz inequality , which is itself a generalization of the triangle inequality .
The triangle inequality states that the length of two sides of any triangle, added together, will be equal to or greater than the length of the third side. ... | https://en.wikipedia.org/wiki/Kantorovich_inequality |
The Kantorovich theorem , or Newton–Kantorovich theorem, is a mathematical statement on the semi-local convergence of Newton's method . It was first stated by Leonid Kantorovich in 1948. [ 1 ] [ 2 ] It is similar to the form of the Banach fixed-point theorem , although it states existence and uniqueness of a zero rathe... | https://en.wikipedia.org/wiki/Kantorovich_theorem |
In gas dynamics , the Kantrowitz limit refers to a theoretical concept describing choked flow at supersonic or near-supersonic velocities. [ 1 ] When an initially subsonic fluid flow experiences a reduction in cross-section area, the flow speeds up in order to maintain the same mass-flow rate, per the continuity equati... | https://en.wikipedia.org/wiki/Kantrowitz_limit |
The Kanzelhoehe Solar Observatory or KSO is an astronomical observatory affiliated with the Institute of Geophysics, Astrophysics and Meteorology out of the University of Graz . [ 1 ] It is located near Villach on the southern border of Austria .

Kaonic hydrogen is an exotic atom consisting of a negatively charged kaon orbiting a proton .
Such particles were first identified, through their X-ray spectrum , at the KEK proton synchrotron in Tsukuba , Japan in 1997. [ 1 ] More detailed studies have been performed at DAFNE in Frascati , Italy . [ 2 ] [ 3 ] Kaonic ... | https://en.wikipedia.org/wiki/Kaonic_hydrogen |
Kaonium is an exotic atom consisting of a bound state of a positively charged and a negatively charged kaon . Kaonium has not been observed experimentally and is expected to have a short lifetime on the order of 10 −18 seconds . [ 1 ] [ 2 ]

The Kapitza–Dirac effect is a quantum mechanical effect consisting of the diffraction of matter by a standing wave of light, [ 1 ] [ 2 ] [ 3 ] in complete analogy to the diffraction of light by a periodic grating, but with the role of matter and light reversed.
The effect was first predicted as the diffraction of ele... | https://en.wikipedia.org/wiki/Kapitsa–Dirac_effect |
The Kapitza number ( Ka ) is a dimensionless number named after the prominent Russian physicist Pyotr Kapitsa (Peter Kapitza). He provided the first extensive study of the ways in which a thin film of liquid flows down inclined surfaces. [ 1 ] Expressed as the ratio of surface tension forces to inertial forces, the Kap... | https://en.wikipedia.org/wiki/Kapitza_number |
In mathematics , Kaplansky's theorem on quadratic forms is a result on simultaneous representation of primes by quadratic forms . It was proved in 2003 by Irving Kaplansky . [ 1 ]
Kaplansky's theorem states that a prime p congruent to 1 modulo 16 is representable by both or none of x 2 + 32 y 2 and x 2 + 64 y 2 , wher... | https://en.wikipedia.org/wiki/Kaplansky's_theorem_on_quadratic_forms |
The Kaplan–Meier estimator , [ 1 ] [ 2 ] also known as the product limit estimator , is a non-parametric statistic used to estimate the survival function from lifetime data. In medical research, it is often used to measure the fraction of patients living for a certain amount of time after treatment. In other fields, K... | https://en.wikipedia.org/wiki/Kaplan–Meier_estimator |
In applied mathematics, the Kaplan–Yorke conjecture concerns the dimension of an attractor , using Lyapunov exponents . [ 1 ] [ 2 ] By arranging the Lyapunov exponents in order from largest to smallest λ 1 ≥ λ 2 ≥ ⋯ ≥ λ n {\displaystyle \lambda _{1}\geq \lambda _{2}\geq \dots \geq \lambda _{n}} , let j be the largest i... | https://en.wikipedia.org/wiki/Kaplan–Yorke_conjecture |
The kappa effect or perceptual time dilation [ 1 ] is a temporal perceptual illusion that can arise when observers judge the elapsed time between sensory stimuli applied sequentially at different locations. In perceiving a sequence of consecutive stimuli, subjects tend to overestimate the elapsed time between two succe... | https://en.wikipedia.org/wiki/Kappa_effect |
In biology, Kappa organism or Kappa particle refers to inheritable cytoplasmic symbionts , occurring in some strains of the ciliate Paramecium . Paramecium strains possessing the particles are known as "killer paramecia". They liberate a substance also known as paramecin [ 1 ] [ 2 ] into the culture medium that is leth... | https://en.wikipedia.org/wiki/Kappa_organism |
