It's things like this that help me to remember how very little I know about mathematics. I looked about halfway down and saw that I didn't have the slightest idea what any of them were talking about. I console myself with the thought that there are other subject matters that I am an expert in that they are not. Probably.
- BrandoElFollito 5y agoNo worries. I have a PhD in physics and understand a small fraction as well. Some I have no idea where to place (even though I went though extended math, and I quite like the subject).
- opportune 5y agoFor most of these you’d likely be able to understand the concept at a good enough level to see the contradiction if you looked up the definition of the concepts. For example I think the one about tr(AB)=tr(BA) not holding for arbitrary permutations across a set of more than two matrices is something you could try proving yourself.
