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
