• The Tensor Evaluation Map. For each $X,Y\in \text{Obj}\webleft (\mathsf{Sets}_{*}\webright )$, we have a map
    \[ \mathrm{ev}^{\odot }_{X,Y}\colon \mathsf{Sets}_{*}\webleft (X,Y\webright )\odot X\to Y, \]

    natural in $X,Y\in \text{Obj}\webleft (\mathsf{Sets}_{*}\webright )$, and given by

    \[ \mathrm{ev}^{\odot }_{X,Y}\webleft (f\odot x\webright )\mathrel {\smash {\overset {\mathclap {\scriptscriptstyle \text{def}}}=}}f\webleft (x\webright ) \]

    for each $f\odot x\in \mathsf{Sets}_{*}\webleft (X,Y\webright )\odot X$.
