 Aug 23 revised Convex sequences and Integral representation for the generating function deleted 328 characters in body Aug 23 comment Convex sequences and Integral representation for the generating function Oops, you're right about the convexity, I hope it can fix that it is still bounded. You're also right on the positivity. Now I only get a complex valued measure. I hope it is fixable. Sorry for all the corrections, I thought I give it a shot since it was open for several days already, I will think about it some more and if it is not fixable I'll delete it.

Aug 23 comment Convex sequences and Integral representation for the generating function Okay, I see. By the way, I still didn't give an argument why $L$ is bounded, but the convexity does that (I think). I will think about it a little more, probably it is fixable one way or the other. Do you know of the existence of the Hausdorff Moment Problem? Your problem made me think of that.

Aug 19 comment Measurable Functions behaviour on $\mathbb{R}^{2}$ Ah, yes, the function you construct is a common counterexample (In PDE), that I didn't think of that myself :). Nice! It looks correct to me. It is a different approach than mine, so I'm curious if mine works too. Aug 18 comment Free introductory resources for learning algebra? I assume you mean the version that isn't called "abstract algebra" and is about groups and such (Lang's book is about that) For self-study I'd suggest you take a look at the Schaum's series about algebra, they are cheap, full of examples and exercises.
