The Role of Semirings in Incremental View Maintenance

cs.DB · 2026-06-05 · unverdicted · novelty 8.0

For insert-only IVM of self-join-free conjunctive queries over semirings without additive inverses (natural, provenance, covariance, tropical), amortized constant update time plus constant delay holds iff the query is α-acyclic p-hierarchical.

Determination Provenance: From Ambiguity to Algebra

cs.DB · 2026-06-09 · unverdicted · novelty 7.0

Determination provenance models tuple supports as elements of a commutative semiring under layered resolutions, inducing a filtration that positive relational algebra respects and that unifies isolation levels with negation semantics.
