   \begin{section}{Euclidean Jordan algebras}
     The Jordan product of $x$ and $y$ in some Euclidean Jordan algebra
-    is $\jp{x}{y}$.
+    $V$ is $\jp{x}{y}$. The Jordan-automorphism group of $V$ is
+    $\JAut{V}$. Two popular operators in an EJA are its quadratic
+    representation and ``left multiplication by'' operator. For a
+    given $x$, they are, respectively, $\quadrepr{x}$ and
+    $\leftmult{x}$.
