| - | To prove properties about a list, sequences are used as abstract values. In the following example, $\alpha$ and $\beta$ denote sequences, and $\epsilon$ denotes an empty sequence. To describe the representation of a singly-linked list we write $\mbox{list}(\alpha,i,j)$ where where there is a list segment from //i// to //j// representing the sequence $\alpha$ | + | To prove properties about a list, sequences are used as abstract values.
