 Nov13 awarded Popular Question May12 accepted Show that the set of all minimum points of a convex function over a convex set is convex May12 comment Show that the set of all minimum points of a convex function over a convex set is convex Thank you. Should the right side in $f(x)\leq (\lambda x+(1-\lambda)y)$ not be $f(\cdot)$? I.e. $f$ missing?

I have already tried that. I'll update my question with the steps, where I got stuck. Apr19 comment How to calculate the gradient of matrix equation @J.M.: Yes, assume $b$ is a constant, i.e. unknown, but fixed for the differentiation regarding $a$.
