Example 6.2.12. Elements of $\tilde{L}(\sigma)$ correspond to intersections in a representing diagram. Given $(i_{1},i_{2})\in\tilde{L}(\sigma)$, the element $\sigma^{i_{1},i_{2}}$ correspond to the diagram obtained by smoothing the intersection point corresponding to $(i_{1},i_{2})$. If $(i_{1},i_{2}){\not\in}\tilde{D}(\sigma)$, the element associated to the diagram will vanish in ${\mathcal{H}}_{n}$.
