Simply, it is a method for transforming a polynomial equation of degree with some nonzero intermediate coefficients, , such that some o... |
https://en.wikipedia.org/wiki/Chowla%E2%80%93Mordell%20theorem | In mathematics, the Chowla–Mordell theorem is a result in number theory determining cases where a Gauss sum is the square root of a prime number, multiplied by a root of unity. It was proved and published independently by Sarvadaman Chowla and Louis Mordell, around 1951.
In detail, if is a prime number, a nontrivial... |
https://en.wikipedia.org/wiki/Chowla%E2%80%93Selberg%20formula | In mathematics, the Chowla–Selberg formula is the evaluation of a certain product of values of the gamma function at rational values in terms of values of the Dedekind eta function at imaginary quadratic irrational numbers. The result was essentially found by and rediscovered by .
Statement
In logarithmic form, the ... |
https://en.wikipedia.org/wiki/Class%20number%20problem | In mathematics, the Gauss class number problem (for imaginary quadratic fields), as usually understood, is to provide for each n ≥ 1 a complete list of imaginary quadratic fields (for negative integers d) having class number n. It is named after Carl Friedrich Gauss. It can also be stated in terms of discriminants. Th... |
https://en.wikipedia.org/wiki/Large%20Electron%E2%80%93Positron%20Collider | The Large Electron–Positron Collider (LEP) was one of the largest particle accelerators ever constructed. It was built at CERN, a multi-national centre for research in nuclear and particle physics near Geneva, Switzerland.
LEP collided electrons with positrons at energies that reached 209 GeV. It was a circular coll... |
https://en.wikipedia.org/wiki/Collider | A collider is a type of particle accelerator that brings two opposing particle beams together such that the particles collide. Colliders may either be ring accelerators or linear accelerators.
Colliders are used as a research tool in particle physics by accelerating particles to very high kinetic energy and letting th... |
https://en.wikipedia.org/wiki/Hartley%20transform | In mathematics, the Hartley transform (HT) is an integral transform closely related to the Fourier transform (FT), but which transforms real-valued functions to real-valued functions. It was proposed as an alternative to the Fourier transform by Ralph V. L. Hartley in 1942, and is one of many known Fourier-related tran... |
https://en.wikipedia.org/wiki/Relatively%20compact%20subspace | In mathematics, a relatively compact subspace (or relatively compact subset, or precompact subset) of a topological space is a subset whose closure is compact.
Properties
Every subset of a compact topological space is relatively compact (since a closed subset of a compact space is compact). And in an arbitrary topol... |
https://en.wikipedia.org/wiki/Gas%20chromatography | Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture. In preparative chromat... |
https://en.wikipedia.org/wiki/Particle-in-cell | In plasma physics, the particle-in-cell (PIC) method refers to a technique used to solve a certain class of partial differential equations. In this method, individual particles (or fluid elements) in a Lagrangian frame are tracked in continuous phase space, whereas moments of the distribution such as densities and cur... |
https://en.wikipedia.org/wiki/Just-noticeable%20difference | In the branch of experimental psychology focused on sense, sensation, and perception, which is called psychophysics, a just-noticeable difference or JND is the amount something must be changed in order for a difference to be noticeable, detectable at least half the time. This limen is also known as the difference limen... |

Central serous retinopathy, a visual impairment
Cheyne–Stokes respiration, an abnormal respiration pattern
Child sex ratio, ratio between female and male births
Class switch recombination, a process that changes the constant region of an immunoglobulin

https://en.wikipedia.org/wiki/Tree%20traversal | In computer science, tree traversal (also known as tree search and walking the tree) is a form of graph traversal and refers to the process of visiting (e.g. retrieving, updating, or deleting) each node in a tree data structure, exactly once. Such traversals are classified by the order in which the nodes are visited. T... |
