  2. Gamma matrices - Wikipedia

    en.wikipedia.org/wiki/Gamma_matrices

    The extension to 2n + 1 (n integer) gamma matrices, is found by placing two gamma-5s after (say) the 2n-th gamma-matrix in the trace, commuting one out to the right (giving a minus sign) and commuting the other gamma-5 2n steps out to the left [with sign change (-1)^2n = 1].

  3. Census tract - Wikipedia

    en.wikipedia.org/wiki/Census_tract

    A census tract, census area, census district or meshblock [1] is a geographic region defined for the purpose of taking a census. [2] Sometimes these coincide with the limits of cities, towns or other administrative areas [2] and several tracts commonly exist within a county.

  4. Gamma distribution - Wikipedia

    en.wikipedia.org/wiki/Gamma_distribution

    Suppose we wish to generate random variables from Gamma(n + δ, 1), where n is a non-negative integer and 0 < δ < 1. Using the fact that a Gamma(1, 1) distribution is the same as an Exp(1) distribution, and noting the method of generating exponential variables, we conclude that if U is uniformly distributed on (0, 1], then −ln U is ...

    Acres Homes Multi-Service Center. Acres Homes is a neighborhood located in northwest Houston, Texas. The 9-square-mile (23 km 2) mile area is loosely bounded by the city limits and West Gulf Bank Road to the north; Pinemont Drive to the south; North Shepherd Drive to the east; and Alabonson Drive to the west. Historically, it has been ...

  6. Inverse-gamma distribution - Wikipedia

    en.wikipedia.org/wiki/Inverse-gamma_distribution

    Inverse gamma distribution is a special case of type 5 Pearson distribution; A multivariate generalization of the inverse-gamma distribution is the inverse-Wishart distribution. For the distribution of a sum of independent inverted Gamma variables see Witkovsky (2001)

    It is unknown whether these constants are transcendental in general, but Γ(⁠ 1 / 3 ⁠) and Γ(⁠ 1 / 4 ⁠) were shown to be transcendental by G. V. Chudnovsky. Γ(⁠ 1 / 4 ⁠) / 4 √ π has also long been known to be transcendental, and Yuri Nesterenko proved in 1996 that Γ(⁠ 1 / 4 ⁠), π, and e π are algebraically independent.

  8. Holmes Run Acres - Wikipedia

    en.wikipedia.org/wiki/Holmes_Run_Acres

    Meticulous site planning, including the architects' subdivision of the land into irregularly-sized and shaped lots, was "an important factor in the general attractiveness of Holmes Run Acres." [7] Homes in Holmes Run Acres were constructed in three phases between 1951 and 1960: Luria Brothers Development - approximately 260 homes during 1951–52.

  9. Higher-dimensional gamma matrices - Wikipedia

    There are 2 d such products, but only N 2 are independent, spanning the space of N × N matrices. Typically, Γ ab provide the (bi)spinor representation of the ⁠ 1 / 2 ⁠ d(d − 1) generators of the higher-dimensional Lorentz group, SO + (1, d − 1), generalizing the 6 matrices σ μν of the spin representation of the Lorentz group in ...
