I'm an undergraduate math major (rising junior) at an institute that is not particularly known for the pure sciences - although it is very reputed for technology and engineering areas. That being said, the math department is decently good in that there's (some) good faculty, graduate courses are offered, etc. Also, I realized my interest in pure mathematics a little late (or I probably wouldn't have decided to go through with undergrad at this institution) - but it has become concrete now, and I am very sure of applying to graduate school in pure mathematics.

Almost all the students at my institution are not interested in or fascinated by pure mathematics, and I have been unable to find a peer group of students I can talk about math with. I think such a group is really important for the following reasons: (i) it's a good way to brainstorm on hard problems, rather than being stuck alone, (ii) it's a good way to develop an intuition of abstract concepts and see the same things via different perspectives, (iii) as an undergrad, studying graduate-level courses with a motivated and interested peer group can be more effective than going through them alone.

That's all that I think of off the top of my head, but I think we can safely conclude that the advantages of studying pure mathematics with a like-minded peer group are way too many compared to studying it alone. I have a good relationship with my professors, who are very helpful, but they are certainly not a substitute for a peer group of mathematically inclined students around my age.

Is there any way I can remedy this? How do I interact with others* interested in mathematics, as an undergraduate? I would love to meet other undergrads who would be happy to discuss math and learn together, in some sense.

*Since this doesn't seem to be an option at my home institution, the next best way would be to develop meaningful connections with like-minded undergrads from other institutions - but I do not know how to do this or if it's even possible.

Thank you for reading. I would appreciate your insights and help!
