Oct 14, 2022 at 19:45 | comment | added | Dan Doel | The point here is that for elements to be 'of the form $σ:s$,' means not just that there is any old function of type $\mathcal{E} → Σ×\mathcal{E}$. The point is to characterize it in such a way that bisimilarity coincides with set theoretic equality. For examples like this, some amount of encoding is going to be necessary unless non-well-founded sets are allowed. But the point is to be considering sets of traces, not carrier sets of any algebra. | |
