If only I knew what a tensor product was
Took me a while to find out what I think these all are, still not 100% on some of them. From top left, going right:
- Multiplication over the rationals
- Wedge product / alternating product
- Function composition (ring operator)
- Inner product (e.g. scalar product)
- Tensor product
- Lie bracket
- Set intersection
- Vector product / cross product
- Tor functor
Corrections welcome!
The third is actually group opertor, but function composition’s not bad either :D
what is the thing at the top of the middle column
Ahould be alternating product, is a bit fucksd, will fix
