So Shin Tun Yao, who is a um a very, you know, is again a uh very much like a mentor to me.
Uh and he got the he gets the fields matter immediately.
Right, so we can see why this is so important.
He gets the fields medal because this idea falling through Klabi is trying to generalize this this sequence of ideas of Euler, Riemann, and uh Euler, Gauss, and Riemann.
So it's certainly, certainly very important.
So there it is.
We can park park this idea.
So so Yao showed that there there are these.
Khler manifolds that that have this property, that have the right metrical properties.
So by metric I mean distance, you know, something you can integrate over.
That that you go because here, you know, you you never think you that this this integral is messy, right?
Even if you do this on a sphere, right?
This this R has all these cosines and signs that have got the you know, you they've all got to cancel at the end of the day to give four pi.
Like what the hell?
And then divided by two pi, you get two, and that's the Euler number, which is kind of amazing stuff.
And now you can do this in general.
The the the just as a caveat, um, Yao showed that this metric exists.
He never actually gave you a metric.
So the only currently known metric on these things is uh is for for the zero curvature case, it's just the just just the torus.
Anything above that, we we don't know.
