Function field may refer to:
*
Function field of an algebraic variety In algebraic geometry, the function field of an algebraic variety ''V'' consists of objects that are interpreted as rational functions on ''V''. In classical algebraic geometry they are ratios of polynomials; in complex geometry these are meromorp ...
*
Function field (scheme theory) The sheaf of rational functions ''KX'' of a scheme ''X'' is the generalization to scheme theory of the notion of function field of an algebraic variety in classical algebraic geometry. In the case of algebraic varieties, such a sheaf associates to ...

Algebraic function field
In mathematics, an algebraic function field (often abbreviated as function field) of ''n'' variables over a field ''k'' is a finitely generated field extension ''K''/''k'' which has transcendence degree ''n'' over ''k''. Equivalently, an algebrai ...

Function field sieve In mathematics the Function Field Sieve is one of the most efficient algorithms to solve the Discrete Logarithm Problem (DLP) in a finite field. It has heuristic subexponential complexity. Leonard Adleman developed it in 1994 and then elaborated ...
