 Identifiers are used to name different kinds of language objects such as nodes, hyperedges or variables. Identifiers may contain letters, numbers, underscores, and dollar signs but must begin with a letter or an underscore.
 Accordingly, the following identifiers are all valid,
 
-.. math::
-    :nowrap:
+.. centered::
 
-    \begin{align*}
-        \texttt{mynode1}, \qquad \texttt{_SolarPlant_2}, \qquad \texttt{HydroStorage_a}.
-    \end{align*}
+        ``mynode1``, \qquad ``_SolarPlant_2``, \qquad ``HydroStorage_a``.
 
 Besides these lexical requirements, identifiers must also be unique in their respective scope. Hence, no two nodes may have the same identifier since this would prohibit the unambiguous identification of a particular node.
 Similarly, variables and parameters may not have the same identifier as a node or other variables and parameters belonging to the same node.
