We kicked off with a new thematic programme on #SpectralTheory 2 weeks ago, but the 1st focus week is happening 🔜.
Are you joining? 😉
As you could expect, you can reach the schedule and more at https://esi.ac.at/events/e425/ and the talks on our YT Channel at https://youtube.com/@ESIVienna/featured

Thinking like a mathematician.
For future reference, here's the master 🧵 by @tao on what it "suffices to check" to prove whether a particular invariant is preserved. https://mathstodon.xyz/@tao/109451634735720062
Note that he starts with #HilbertSpaces, but downthread he extends the principle more broadly.
