Kimi Delta Attention utilizes bra-ket notation for clarity in mathematical derivations, where column vectors represent states, row vectors represent duals, numbers represent scalars, and matrices represent linear transformations. In this notation, vectors are oriented to the right by default, while keys are oriented to the left within the linear attention structure.
