@HarryGindi BTW Chatjax works on mobile (at least on firefox mobile, dunno about other setups)

What would be a good reference to use for a studying seminar on the EHP sequence? There are several sources I know that deal with the vector fields differential but not a lot about how to use all the tricks and schtiks with toda brackets, whitehead brackets to squeeze out differentials in low degrees. From my understanding it should be possible to go pretty high stemwise using only the hopf maps and algebraic considerations... besides Toda's book are there any other references for this?
Asking for a friend of course ^^

@DenisNardin Do you have a link to how to set it up?
 
As usual: go to math.ucla.edu/~robjohn/math/mathjax.html , save it as a bookmark
(if your browser is annoying there's a special section to deal with that but I did not have to do it)
When you want to apply it, tap on the address bar, go to bookmarks and press on the bookmark

Are there any interesting homotopy theory seminars happening online this fall? I'm doing grad school in music so I won't be connected to a math department, but I want to stay in touch with the homotopy theory community :)
 
I think at quite a few universities their "standard" weekly topology seminars will be happening online, as far as I know this will be the case at MIT for example, with talks being announced on researchseminars.org.
A good way to stay in touch with the community is the Alg-Top-L mailing list (lehigh.edu/~dmd1/algtop.html), larger new conferences or seminar series are almost always announced there.

@SaalHardali there have been two "juvitop"s on EHP in the past decade. neither is super great as a reference (one has some notes / references, the other has essentially nothing), but i thought i'd mention them all the same
the individuals involved might have some notes / pointers beyond what's offered on the websites
 
5:17 PM
@EricPeterson I have notes for one of those juvitops but frankly I wouldn't recommend them... it was probably the juvitop I understood the least (despite it being one of those I would have loved to learn more about)
 
5:35 PM
do those notes have references beyond toda? that might already be useful, even if the "bulk" of the notes is questionable
 
5:54 PM
I don't think so, I'll check later

@EricPeterson @DenisNardin Thanks for the effort. It does feel kind of odd that the only comprehensive reference for this stuff is a book from the sixties. That can't be true right?
Maybe there are later papers that cover this stuff to some extent? Unfortunately when I look at papers from the 70-80's that have EHP in their title i usually get lost pretty quick (unless it's about the diagonal, the vector field differentials or in this general vicinity).
