1 definition found From The Free On-line Dictionary of Computing (05 January 2017) [foldoc]: eta conversion eta abstraction eta expansion eta reduction In lambda-calculus, the eta conversion rule states \ x . f x <--> f provided x does not occur as a free variable in f and f is a function. Left to right is eta reduction, right to left is eta abstraction (or eta expansion). This conversion is only valid if bottom and \ x . bottom are equivalent in all contexts. They are certainly equivalent when applied to some argument - they both fail to terminate. If we are allowed to force the evaluation of an expression in any other way, e.g. using seq in Miranda or returning a function as the overall result of a program, then bottom and \ x . bottom will not be equivalent. See also observational equivalence, reduction.
