Valda Seminar : Val Tannen
Val Tannen, University of Pennsylvania 21 February 2020, 10:00-11:00 ENS, S16 Provenance Analysis for First-order Model Checking Is a given finite structure a model of a given first-order sentence? The provenance analysis of this question determines how its answer depends on the atomic facts that determine the structure. Provenance questions…
