I never think about it. Thanks on your response!!!

I was thinking about famous open problems.

I know some:

P = NP or P !=NP

Zeta function

I was thinking that every mathematicians know a little. So I was wrong.

But thanks to you this post for me is not just, it is more. **I know that in Israel there are articles on open problems.**

**I like to read on open problems and I was thinking that else people do it.**

**Well, I try in the next post or other will try [but I not meant to overflow the forum] to describe an open problems that it is known.**

**I was thinking about famous problems.**

**But you are right.**

**I think that in the future, the surf fests will help to find a problem that they know that are open.**

**You are very welcome!!!!**
