boneidol: 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. ?https://en.m.wikipedia.org/wiki/Noncommutative_geometry

boneidol: 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. #math #crypto

boneidol: 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 #Math

boneidol: 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 https://indy.im/notice/20750941
