geometric representations in convex analysis

Question

Do you have any advices that help having geometric representations in convex analysis ? (for instance examples you always keep in mind when you are working, websites with simulations, graphs , ...)

I have found some difficulties when I am following proofs on textbooks.

Thank you.

I think the question is too broad. Some more context might help: what level of convex analysis are you dealing with? Euclidean space $\mathbb R^n$? Banach spaces?

One general piece of advice: in many cases (though not all), the important features can be visualized in two dimensions. If at all possible, try to picture the situation in two dimensions or in a two-dimensional slice of a larger space.

thanks for your answer. My setting is generally $\mathbb{R}^n$ – user2015 Jul 16 '15 at 00:19
