Logical Approaches to Non-deterministic Polynomial Time over Semirings
Timon Barlag, Nicolas Fröhlich, Teemu Hankala +6
We provide a logical characterization of non-deterministic polynomial time defined by BSS machines over semirings via existential second-order logic interpreted in the semiring sem…
Locally Consistent K-relations: Entailment and Axioms of Functional Dependence
Timon Barlag, Miika Hannula, Juha Kontinen +2
Local consistency arises in diverse areas, including Bayesian statistics, relational databases, and quantum foundations, and so does the notion of functional dependence. We adopt a…
Logic and Computation through the Lens of Semirings
Timon Barlag, Nicolas Fröhlich, Teemu Hankala +6
We study the expressivity and computational aspects of first-order logic and its extensions in the semiring semantics developed by Grädel and Tannen. We characterize the complexity…
