Redrot

Does "bad mathematics," as in (edit: to clarify, significant) erroneous mathematics from practicing mathematicians (say e.g. Ph.D. students and up), belong in this subreddit? On the one hand, pointing out (obvious) mistakes in non-peer-reviewed mathematics is a good thing to do, especially for particularly bold claims, but I'm not sure reddit is the place to do it. And on the other hand, shaming a probably well-meaning mathematician anonymously(ish) seems like bad news to me. I want to bring up this topic because there are no rules regarding this, but I imagine there should be.

Part of the context is that I saw a preprint whose math definitely belongs here. If the content wasn't posted on a

In the past 20 years, Advances in Mathematics, one of the well-known, fairly prestigious journals in mathematics, went from publishing under 100 papers a year to roughly around 400 per year. Such growth hasn't been exhibited by other journals of comparable prestige like Crelle's Journal, Compositio Mathematica, and Proceedings of the LMS which have roughly remained steady in their publication count. Despite t

I'm looking for well-written resources for understanding spectral sequences intuitively, and perhaps more importantly, how to use them practically as a working mathematician. I believe I am well-acquainted enough with their definitions, and that I get the notion that they are built to approximate cohomology, but still really have no idea about how they are used, or when one knows that it's time for a spectral sequence argument. Has anyone come across good explanations or uses in papers that elucidate these things? I've gone through Carlson's Cohomology Rings of Finite Groups and Vakil's notes on them in The Rising Sea, but neither's really made them click for me.

Essentially wondering the question in the title, as someone who is waiting on the NSF PRF, as well as a bunch of other postdoc applications. I'm hoping that if the results aren't out by Feb 10, the coordinated date for most departments, job offer deadlines would be extended...

I've been on the search for a bit for good sources of online research-level (or otherwise deep) math communities, blogs, news sites, and social media accounts. In general, there's no shortage of them, although I feel math is still quite lacking compared to other hard science fields.

However, I've had a harder time finding stuff like this specifically for representation theory (and maybe more generally, algebraic fields, though there's no shortage for category theory). Does anyone have some good people or places to follow for stuff in that vein? Yes, I know, "representation theory" has a wide range of subfields, but I'm looking for just about anything, really.

I've arrived at a very exciting point in my Ph.D. program where I'm submitting papers to journals and giving research talks on my work. For the most part, it's been really fun.

However, recently, I've been having a decent amount of stress about having critical errors in papers that I've either put on arXiv or submitted for publication. For the most part, this feels irrational since most of these proofs have been, at some point, looked over by my advisor, and I should have a complete understanding of what I write. But every time I open up my TeX file, I feel like I find a new typo or minor mistake - when you put together 40 pages of math by yourself, it feels like no matter how much you pou

Here's a lil warmup set I recorded for a forest renegade this saturday. Played out some new weapons. Fast, fun, loose, ravey, not too serious.

Tracklist will be posted eventually
