A General Formula on the Conjugate of the Difference of Functions

Abstract Given an arbitrary function g :X → (-∞, +∞] and a lowersemicontinuous convex function h:X → (-∞, +∞], we give the general expression of the conjugate (g — h)* of g - h in terms of g* and h* . As a consequence, we get Toland's duality theorem:
