20 de jun. de 2024 · In mathematics, the gamma function (represented by Γ, the capital letter gamma from the Greek alphabet) is one commonly used extension of the factorial function to complex numbers. The gamma function is defined for all complex numbers except the non-positive integers.
Hace 6 días · gamma function, generalization of the factorial function to nonintegral values, introduced by the Swiss mathematician Leonhard Euler in the 18th century. For a positive whole number n , the factorial (written as n !) is defined by n ! = 1 × 2 × 3 ×⋯× ( n − 1) × n .
Hace 4 días · Gamma ray, electromagnetic radiation of the shortest wavelength and highest energy. Gamma rays are produced in the disintegration of radioactive atomic nuclei and in the decay of certain subatomic particles. It includes some overlap with X-rays in the electromagnetic spectrum.
19 de jun. de 2024 · La radiación gamma consiste en fotones de alta energía y es la más penetrante de las tres. Puede atravesar materiales densos y es la más peligrosa para los seres humanos en términos de exposición externa, ya que puede penetrar fácilmente en el cuerpo y causar daños en el tejido celular.
Hace 3 días · The gamma distribution is the maximum entropy probability distribution (both with respect to a uniform base measure and a / base measure) for a random variable X for which E[X] = kθ = α/β is fixed and greater than zero, and E[ln X] = ψ(k) + ln θ = ψ(α) − ln β is fixed (ψ is the digamma function).
6 de jun. de 2024 · Gamma-ray photons are between 10,000 and 10,000,000 times more energetic than the photons of visible light when they originate from radioactive atomic nuclei. Gamma rays with a million million times higher energy make up a very small part of the cosmic rays that reach Earth from supernovae or from other galaxies .
Hace 6 días · In mathematical physics, the gamma matrices, {,,,} , also called the Dirac matrices, are a set of conventional matrices with specific anticommutation relations that ensure they generate a matrix representation of the Clifford algebra , .
