WebThe epigraph is the set of points laying on or above the function’s graph. A convex function has an epigraph that is a convex set. A convex function has an epigraph that is a convex set. If you’re unfamiliar with epigraphs and convex sets, this image shows you the basic idea behind those terms (Duchi, 2016): WebWhat is true is that every function that is finite and convex on an open interval is continuous on that interval (including Rn). But for instance, a function f defined as f(x) = − √x for x > 0 and f(0) = 1 is convex on [0, 1), but not continuous. – Michael Grant Aug 15, 2014 at 19:33 8

WebJul 26, 2015 · The epigraph of $\mathcal{L}$ is for any given value of $\vec x$ is going to be a convex set, as once $\vec x$ is fixed the function is affine, and affine functions are both convex and concave. If we flip this notion, we can look at negative epigraphs, or the set of points 'below' the function.
