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. jimmy barnes screaming mp3
