 designate the course-of-values of the functions \(f\) and \(g\), respectively. In this notation, the symbols \(\stackrel{,}{\epsilon}\) and \(\stackrel{,}{\alpha}\) bind the object variables \(\epsilon\) and \(\alpha\) in the expressions \(f(\epsilon)\) and \(g(\alpha)\), respectively, and the resulting expression denotes a course-of-values.
