Wikipedia is a bit rubbish on #math.. but this is funny..
I was reading the page on non commutative geometry and spotted this
"A smooth Riemannian manifold M is a topological space with a lot of extra structure"
No shit!
I wondering if I could extend this definition to
<Mathematical object> is a set with a lot of extra structure on it. ?

How can you have a "tangent" to a "curve" when everything is over a discrete field?
I don't believe most of the explanations of elliptic curve cryptography

I just read
S.S. Al-Riyami and K.G. Paterson, Certificateless public key cryptography 2003
https://web.archive.org/web/20181222114112/http://eprint.iacr.org/2003/126.pdf
The math is not too complicated, but I find the notation a pain.
Also, all the fuss over the group operation being additive in G_1 and multiplicative in G_2 seems such a faff.

The lecturer said that for a tensor of rank m over a finite dimensional vector space the number of components is
${m^{dim V}}$
So I looked at that for several hours! and could not understand it.
Well of course I thought about it now and it's obviously ${(dim V)}^m$
But I spent ages trying to convince myself that the incorrect thing was true.
Sometimes you just have to brave

I was watching a lecture last night, about vector spaces and tensors. The lecture was great. I've never been very good at tensors, and struggled at that bit whilst at school. Anyway this lecture made it all super clear, and it was a great introduction to them. HOWEVER the lecturer makes a mistake in a small detail, whilsts discussing the number of components in a tensor with respect … -

I thinking about maybe taking an exchange semester (probably autumn 2018) and I've narrowed the list down to Scotland and Germany, in particular; - University of Edinburgh, - Universität Konstanz, - Humboldt-Universität zu Berlin, - Techn Universität München and - Universität Münster. Anyone got any experience from these or general recommendations? Not sure if my grade… -

goddamnit I feel like I really have to read up some on groups actions. It's such a basic thing but I realize when that when the concept pops up here and there there's a gap in my understanding. I hope it wont take more than like an afternoon to relearn the fundamentals. !math
