Also known as: gamma, uppercase gamma, big gamma, greek gamma, gamma function symbol, upside down l, gama.

The Greek capital letter Gamma (Γ) names the gamma function, which extends the factorial to real and complex arguments through an integral definition. In geometry and physics it may denote a curve or contour, for example a path of integration in the complex plane. It also labels connection coefficients (Christoffel symbols) in differential geometry.

\Gamma(n) = (n - 1)!

Also known as: greek gamma, lowercase gamma, small gamma, gamma letter, lorentz factor, euler mascheroni constant, gamma ray symbol, y looking greek letter.

Gamma is the third letter of the Greek alphabet, and its lowercase form γ is widely used in mathematics, physics, and engineering. It denotes the Lorentz factor in special relativity, the Euler–Mascheroni constant in analysis, and angles in geometry. In physics γ also names gamma rays and the photon, and in imaging it labels the gamma correction curve of displays.

\gamma = \frac{1}{\sqrt{1 - v^2/c^2}}
