In mathematics, a real-valued function is called convex if the line segment between any two distinct points on the graph of the function lies above the graph between the two points. Equivalently, a function is convex if its epigraph (the set of points on or above the graph of the function) is a convex set. A twice … See more Let $${\displaystyle X}$$ be a convex subset of a real vector space and let $${\displaystyle f:X\to \mathbb {R} }$$ be a function. Then $${\displaystyle f}$$ is called convex if and only if any of … See more The term convex is often referred to as convex down or concave upward, and the term concave is often referred as concave down or convex upward. If the term "convex" is used … See more The concept of strong convexity extends and parametrizes the notion of strict convexity. A strongly convex function is also strictly convex, but not vice versa.
