We tackle this task by introducing a notion of temporal core decomposition where each core is associated with its span: we call such cores span-cores.\n  As the total number of time intervals is quadratic in the size of the temporal domain $T$ under analysis, the total number of span-cores is quadratic in $|T|$ as well.
