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
