Introducing Math Problem of the Week

[I like Serena]

@Euge! You've made it over here! Thank you for joining!

You're pretty much the smartest mathematician that I've ever seen and I've always been impressed that you were willing to put up the university and graduate POTW's on a regular basis.
So I hope the people here will welcome you, and give your problems at least a try. I won't hold my breath if they can solve your graduate POTW's though, or even your university POTW's.

Thanks! Well, I suspect that several members are capable of solving both of the advanced POTWs, considering the mathematical talent displayed on this site.

Welcome to the PF @Euge! It is exciting to have somebody with your abilities joining the forum!

I have a PhD in theoretical physics and enjoy tackling undergraduate maths problems. But I fear that your postgraduate problems will be beyond me. Just checking, so you will you be giving us 2 weeks to solve the problems?

 

[Euge]

Thanks @julian! I will not be so stringent with the POTW. If no one answers the POTW in 2 weeks, then I will post my solution. Other solutions are still welcome after the two-week period.

Graduate POTW just kicked off today!

Hi @Greg,

Perhaps now you make an update in the announcement, since things have been finalized with me (unless there is something else that is needed).

done!

Not that it matters much, but it looks like the featured post didn't change with the edits made to the initial post.

The OP also only has a link to the high school POTW, and not the University or Graduate POTW.

POTW threads now have an official prefix

It would be great if the POTW threads could find a place on the right panel. When fresh42 was managing the Math Challenges, I remember three threads pinned to the right panel. Something similar could be done for the POTW threads too...

Good idea, I can do this

Ok the widget has been added to the homepage sidebar

I'm so happy that @anemone and @Euge continue on their great work here at PF. Seeing how many people just respond to this announcement makes me smile. A community needs members of all sorts to thrive - those who ask, those who help, those who coordinate, those who lurk. PF looks to have a nice size of all of these.

The collaborations in the POTW threads are beautiful to see! So fun!
