This Subreddit MATH COMPETITION: r/mathmemes Discord Community Exam

104 Upvotes

Hello!

To make up for the lack of an "upper division" in the subreddit math competition this year, I took it upon myself to organize a separate exam that is significantly more discovery and proof-based than any exam held in the community previously, and to host it on the 2nd year anniversary of the Discord server being made available to the public.

The next exam of this kind will be held in Mid-June 2027.

The exam (which includes its rules) is linked at the bottom of the post. The top 5 winners will be announced, and the top 3 winners will receive the following (or something of equivalent value upon negotiation):

1st Place - A Math Textbook of the Winner's Choice (~$45 USD Value Limit)

2nd Place - Basic Discord Nitro, 1 Year Subscription ($30 USD Value)

3rd Place - Fulltouch Hagoramo Chalk 72 pc ($25 USD Value)

Special thanks to u/dopplerspectroscopy and zzz on Discord for their tremendous help in writing the exam and agreeing to help grade some submissions; couldn't have done this without their help.

Presenting, the Indiana radian!

2πœ‹ Indiana radians make a circle, not to be confused with a normal radian, where 2πœ‹ normal radians make a circle.

The image is a comparison between 1 Indiana radian (orange) and 1 normal radian (red).

Mathematicians Grothendieck work seem like the Bible of some notorious cult (which I'm part of)

Motives are objects developed by Grothendieck as a part of a generalized cohomology theory. His work was mainly motivated by ordinary cohomologies having similar properties. Except, 99% of the theory are just conjectures that are still open since decades. The most notorious of them is the motivic Riemann hypothesis for motivic L functions which are supposed to generalize L functions including Riemann zeta functions. Except to this day, absolutely nothing I known about those L functions.

Proofs I present, half a circle!

Half the points were removed from this circle, so it is half a circle.

(also i do not know what flair to put so have the proofs flair)

Bad Math I haven't seen it written like this yet

But if you get a bit serious and try to group numbers to see if the sum would actually fit it goes like this:

1 + 13 + 169 + 2197 + ...

1 + (3+4+6) + (7+...+19) + (20+...+27+29+...+69) + ...

and numbers like 2, 5, 28, 149, ... don't get used as far as I checked

One year ago today (https://www.reddit.com/r/mathmemes/s/rQK6sjxhME) I declared November 13th to be Integer Appreciation Day, and, lo and behold, that day has come around again.

Consider showing the set some love, perhaps by completing a few proofs highlighting them.
