I hope you will! The specific math stuff with which you were just confronted is neither pertinent nor a limiting factor regarding the thoughts you posted on this topic. I think there's a little bit of "troll" in several of us here...(not me, though).

If we see a PhD limiting himself (or herself) to posting about the topic of their doctoral thesis (or post-doc work), I will be shocked!

Sincerely,
Mike
