§ Tensor Hom Adjunction

created 2021-01-09
  • (- X A) witnesses A as an output, while Hom(A, -) witness A as input.
  • Similarly, we know that we can contract A with A* so it makes sense that the "dual" of multiplying by A (ie, how to divide out A) is to invert it by allowing a contraction with A*.
