Lambda function

Lambda function may refer to:

Mathematics

 * Dirichlet lambda function, λ(s) = (1 – 2−s)ζ(s) where ζ is the Riemann zeta function
 * Liouville function, λ(n) = (–1)Ω(n)
 * Von Mangoldt function, Λ(n) = log p if n is a positive power of the prime p
 * Modular lambda function, λ(τ), a highly symmetric holomorphic function on the complex upper half-plane
 * Carmichael function, λ(n), in number theory and group theory

Computing

 * Lambda calculus, in computer science
 * Lambda function (computer programming), or lambda abstraction
 * AWS Lambda, a form of serverless computing

Physics

 * Källén function, λ(x,y,z), also known as triangle function, a symmetric polynomial that occurs in particle physics.
