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.
LINQ - Lambda Expressions. The term âLambda expressionâ has derived its name from âlambdaâ calculus which in turn is a mathematical notation applied for defining functions. Lambda expressions as a LINQ equationâs executable part translate logic in a way at run time so it can pass on to the data source conveniently. However, lambda expressions are not just limited to find application in LINQ only. The above expression specifies a parameter named y and that value of y is squared. However, it is not possible to execute a lambda expression in this form. Example of a lambda expression in C# is shown below.
