Lambda calculus. Lambda calculus (also written as Î»-calculus) is a formal system in mathematical logic for expressing computation based on function abstraction and application using variable binding and substitution.
The token is called the lambda operator. It is used in lambda expressions to separate the input variables on the left side from the lambda body on the right side. Lambda expressions are inline expressions similar to anonymous methods but more flexible; they are used extensively in LINQ queries that are expressed in method syntax.
