@@ -297,7 +297,7 @@ The trick is to find a Hermitian operator $\hat{L}$ (usually using
 symmetries of the system) which commutes with both $\hat{H}_0$ and $\hat{H}_1$:
 
 $$\begin{aligned}
-    \comm*{\hat{L}}{\hat{H}_0} = \comm{\hat{L}}{\hat{H}_1} = 0
+    \comm*{\hat{L}}{\hat{H}_0} = \comm*{\hat{L}}{\hat{H}_1} = 0

 So that it shares its eigenstates with $\hat{H}_0$ (and $\hat{H}_1$),
