Once upon a time, guided by a whisper of intuition—or perhaps a playful nudge from fate—we set out on a journey. At first, our quest seeme... -
Every good story deserves a happy ending. After all, nobody wants to be left with frustration—especially during the holidays! So, on this... -
Today it is short. Just to inform my readers, that I have just finished collecting my posts on Lie sphere geometry published so far into a ...
Good morning! I'm so glad Bjab has rejoined the renewed blog.
ReplyDeleteSorry for missing two posts, but I was busy exploring a recently discovered connection between seemingly distant things:
the Indian mathematician Ramanujan's algorithms for expanding pi and modern CONFORMAL field theories.
Yes, that magical conformal invariance again. I don't want to spam the Blog, so I'll just link to the original article:
"Ramanujan's 1/pi Series and Conformal Field Theories" (October 2025) https://arxiv.org/html/2503.21656v3
The math there is quite complicated for me, but there are several links that are much clearer. Virasoro Algebras and many other wonderful things appear there...
After some reflection, I even grasped a very simple idea about why it's so natural for pi to be associated with conformal invariance.
However, I'm not sure it's appropriate to present such primitive ideas here.
