 The first three equations should be self-explanatory. The temporal formula
 \isa{AX\ f} means that \isa{f} is true in all next states whereas
 \isa{EF\ f} means that there exists some future state in which \isa{f} is
-true. The future is expressed via \isa{{\isacharcircum}{\isacharasterisk}}, the transitive reflexive
+true. The future is expressed via \isa{\isactrlsup {\isacharasterisk}}, the transitive reflexive
 closure. Because of reflexivity, the future includes the present.
