(mathematical analysis) Any complex-valued measurable function whose range is finite.

(mathematics) Any function whose value is the solution of a quadratic polynomial

(mathematics) Any function, of multiple variables, whose value is independent of the order of the variables, i.e. f(a,b) = f(b,a).

(physics) The minimum energy needed to remove an electron from the surface of a material

(mathematics, computing) A function whose value is chosen at random from its domain / (mathematics) A function chosen at random from a set of functions

(algebra, logic, computing) Any function based on the operations AND, OR and NOT, and whose elements are from the domain of Boolean algebra

A function which is equal to 1 for all points in its domain which belong to a given set, and is equal to 0 for all points in the domain which do not belong to that given set.

(logic) A function which replaces a variable bound by an existential quantifier which lies in the scope of an even number of logical negations; such function is a function of the remaining bound variables whose scope contain the given variable (being replaced).

(logic) A function which replaces a variable bound by a universal quantifier which lies in the scope of an even number of logical negations; such function is a function of the remaining bound variables whose scope contain the given variable (being replaced).

plural of Lagrangian function
