Convex or convexity may refer to:

Mathematics:

• Convex set, a set of points containing all line segments between each pair of points
• Convex function, a function with the epigraph (the set of points lying on or above the graph) forming a convex set
• Convex polygon, a polygon which forms a convex set
• Convex hull, the minimal convex set containing a set of points X
• Convex combination, a linear combination of points with non-negative coefficients that sum up to 1
• Convex conjugate, is a generalization of the Legendre transformation

Finance: Look up Convex set in Wiktionary, the free dictionary. ... In mathematics, convex function is a real-valued function f defined on an interval (or on any convex subset C of some vector space), if for any two points x and y in its domain C and any t in [0,1], we have Convex function on an interval. ... A convex pentagon In geometry, a convex polygon is a simple polygon whose interior is a convex set. ... Convex Hull: Elastic band analogy // Alternative definitions In mathematics, the convex hull or convex envelope for a set of points X in a real vector space V is the minimal convex set containing X. (Note that X may be the union of any set of objects made of points). ... A convex combination is a linear combination of data points (which can be vectors or scalars) where all coefficients are positive and sum up to 1. ... In mathematics, two differentiable functions f and g are said to be Legendre transforms of each other if their first derivatives are inverse functions of each other: f and g are then said to be related by a Legendre transformation. ...

 convexity - definition of convexity in Encyclopedia (637 words) For example, a solid cube is convex, but anything that is hollow or has a dent in it is not convex. Closed convex sets can be characterised as the intersections of closed half-spaces (sets of point in space that lie on and to one side of a hyperplane). A convex function f defined on some convex open interval C is continuous on the whole C and differentiable at all but at most countably many points.
