Im not doing any studying so much right now but i have a few projects i’m working on, gmt obviously involved in and around the dg
May 14, 2020 18:46
I know who he is but idk him
May 14, 2020 18:45
it’s a good book
May 14, 2020 18:43
maggis book was actually open on my desk before i wandered in here so this discussion is appropriate
May 14, 2020 18:42
yeah
May 14, 2020 18:41
and that’s good because measure convergence is analytically good to talk about
May 14, 2020 18:41
and you can think about rectifiable things as giving you measures (just the hausdorff measure restricted to it) and the push forward of that measure by the blow up maps is gonna converge in the measure theoretic sense to the measure of the plane
May 14, 2020 18:40
the point is just that if you take something rectifiable than a.e. if you blow it up you get a plane

we have italians in our department too
May 14, 2020 18:38
(note this is a lie)
May 14, 2020 18:38
every one Ive ever met in real life is tbh
May 14, 2020 18:36
i thought all italians knew this when they were born
May 14, 2020 18:36
@AlessandroCodenotti this is fine and good
May 11, 2020 22:10
that’s true but i also read more now than i used to
May 11, 2020 22:09
about GH!
May 11, 2020 22:08
smh
May 11, 2020 22:08
@BalarkaSen i open chat to see this shit
May 11, 2020 20:34
@TedShifrin see i did read some!
May 11, 2020 20:32
errors
May 11, 2020 20:32
there are
May 11, 2020 20:31
ch 3
May 11, 2020 20:31
griffithss and harris
May 11, 2020 20:27
you have to do Currents tho
May 11, 2020 20:27
you can do it for the whole differential complex on an n-dim complex manifold
May 11, 2020 20:25
i said up at the top it's all about PDE
May 11, 2020 20:08
nice
May 11, 2020 20:00
how is life for you
May 11, 2020 20:00
zooming with people to do math just isn’t a good replacement
May 11, 2020 19:59
I have a lot of reading projects right now to make up for not being around people doing math all the time and it’s a decent flow but not getting to go to my department really sucks
May 11, 2020 19:59
if I can’t do it in person in fall i’ll suck it up and just do it on zoom
May 11, 2020 19:58
I postponed till fall because I wanted to wait and see if I could do it in person
May 11, 2020 19:52
so @TedShifrin can be happy once and for all
May 11, 2020 19:52
read griffiths and harris with me
May 11, 2020 19:50
not even once
May 11, 2020 19:50
complex analysis
May 11, 2020 19:43
(all hyperbolic though sorry)
May 11, 2020 19:43
if there were none the sky would be full of pde
May 11, 2020 19:43
@Thorgott that's cause of light polution
May 11, 2020 19:42
fuck my copy is buried in a box somewhere
May 11, 2020 19:42
isnt there a cute little paragraph in griffiths and harris about this
May 11, 2020 19:41
1st order elliptic pde are a spook buddy
May 11, 2020 19:39
what i saaid
May 11, 2020 19:39
log r
May 11, 2020 19:37
by line of course i mean circle
May 11, 2020 19:36
bladiblah
May 11, 2020 19:36
integrating 1/z on a line is coming straight from integrating a dirac mass at 0 over the disk
May 11, 2020 19:36
so distributional magic
May 11, 2020 19:35
@BalarkaSen i wonder if there is a PDE kind of pov here, 1/z looks like r/|r|^2 (this is not exactly right ik dont at me) which is the gradient of log|r| which is the fundamental solution to the laplacian
May 11, 2020 19:30
it still pings me
May 11, 2020 19:30
no he doesnt
