 \begin{block}{Pasting diagrams}
 Fix an $n$-category with strong duality $\cC$. A \emph{field} on $\cM$ is a pasting diagram drawn on $\cM$, with cells labelled by morphisms from $\cC$.
 \end{block}
-\begin{example}[$\cC = \text{TL}_d$ the Temperley-Lieb category]
-$$\roundframe{\mathfig{0.35}{definition/example-pasting-diagram}} \in \cF^{\text{TL}_d}\left(T^2\right)$$
-\end{example}
-\begin{block}{}
-Given a pasting diagram on a ball, we can evaluate it to a morphism. We call the kernel the \emph{null fields}.
-\vspace{-3mm}
-$$\text{ev}\Bigg(\roundframe{\mathfig{0.12}{definition/evaluation1}} - \frac{1}{d}\roundframe{\mathfig{0.12}{definition/evaluation2}}\Bigg) = 0$$
