Pretty good exercises, highly recommend

For the last few years I was perfectly happy living in the world of bounded operators…but the time has come. I'm now learning about unbounded operators on Hilbert spaces

Found this in a math text, what does it really mean?

Understanding subharmonic functions and comparing them with harmonic functions is quite fun. I can’t explain

Before ChatGPT and the like, some graduate courses had grades based entirely on homework. Apparently that’s impossible now.

Haven’t studied for an exam in the longest time and I think I forgot how to xD

Every time I try to draw a disc B(x,r) inside a bounded domain D, it ends up looking like a sunny-side-up egg

School is so useless. They should’ve taught me how to file taxes but instead I learnt that every irreducible complex representation of an abelian group is 1-dimensional

I was talking to my students today about optimization for two-variable functions (using the Hessian, etc.) and ended up discovering a whole bunch of memes on the internet. Here’s one:

ℕ⁺ strikes again. I somewhat understand when algebraists use ℕ = {0,1,...} vs. ℕ⁺ = {1,2,...}, but... analysts???

That being said, which one do you prefer and why? I like the 2π in the exponent, with no constants outside

The world would be a better place if everyone used the same normalization of the Fourier transform

The math is getting so intense ChatGPT had to become French

For all of us who were confused about that scene in "Good Will Hunting" when the professor taught Fourier analysis on the board, but assigned an exercise in graph theory at the end of the class.

Perfect title, no notes.

Visiting @IITKanpur soon! It’s been a while

I love Indian food and the culture but I just want to be able to breathe and not have my throat burn. Been in India for the last two months for my Indian wedding and I don't remember the last time I was so sick for such a long time. I'm tired of wearing a mask. I see small

"A fundamental fact of life" (???)

Last talk of 2025!

Somehow my @IndiGo6E flights in the past few days have been on time but my @airindia flight is delayed by an hour 😭 What are the odds? 😂

Heading to Mohali for the DMHA conference! ✈️
