• 10:3310:33, 18 April 2025 diff hist +510‎ N Definition talk:Tensor ‎ Created page with "The implied definition of rank being used here is highly irregular and may be misleading. In particular, a matrix can be thought of as a $2$-tensor. However, this matrix might still have matrix rank $1$ and tensor rank $3$. I would agree that scalars are $0$-tensors and vectors can be thought of as $1$-tensors, but I would not call this rank, nor do I know anyone who works with tensors regularly who would. --~~~~"

• 08:1208:12, 18 April 2025 diff hist +1,242‎ N Talk:Ideal and Zero Locus are Order Reversing ‎ Created page with "Hello! First off, happy to be here and hope I can help. Second, I've run into a bunch of notational issues around the algebraic geometry pages. Since the nullstell is so central and I wrote this to fix an issue there, I ripped the notation from it. I don't really care whether we notate the zero locus (a term which I never really hear used in the field personally, but I know people use it) as $\map Z I$ or $\map V I$. I personally say "vanishing set" so I use $\map V I$ i..."

• 07:4507:45, 18 April 2025 diff hist +324‎ Zero Locus of Vanishing Ideal is Closure ‎ Cleaned up and corrected original proof. There was an error due to a difference in notation. Also removes the need for missing link.
• 07:1607:16, 18 April 2025 diff hist +635‎ Zero Locus of Vanishing Ideal is Closure ‎ Added a proof of this wonderful result! There is a proof from the nullstellensatz, but I think this is more direct.
