TY - JOUR A1 - Dang, Han-Hing A1 - Glück, Roland A1 - Möller, Bernhard A1 - Roocks, Patrick A1 - Zelend, Andreas T1 - Exploring modal worlds T2 - Journal of Logical and Algebraic Methods in Programming N2 - Modal idempotent semirings cover a large set of different applications. The paper presents a small collection of these, ranging from algebraic logics for program correctness over bisimulation refinement, formal concept analysis, database preferences to feature oriented software development. We provide new results and/or views on these domains; the modal semiring setting allows a concise and unified treatment, while being more general than, e.g., standard relation algebra.
