The paper investigates navigability with imperfect information. It shows that the properties of navigability with perfect recall are exactly those captured by Armstrong's axioms from database theory. If the assumption of perfect recall is omitted, then Armstrong's transitivity axiom is...

The paper introduces a notion of a budget-constrained multiagent transition system that associates two financial parameters with each transition: a pre-transition minimal budget requirement and a post-transition profit. The paper proposes a new modal language for reasoning about such a...

The paper proposes a bimodal logic that describes an interplay between coalition strategies and distributed knowledge. Unlike the existing literature, the paper assumes that a strategy must be not only executable but also verifiable. That is, the strategy of a...

This senior project examines the colonial conquest of Indochina on the part of the French during the last half of the 19th century and the first half of the 20th century not purely as a geographical and historical phenomenon, but...

Underneath the historiographical disagreements about military honor and dueling in Imperial Germany there lurks a consensus that most duelists simply internalized the dictates of honor. This article troubles that presumption by attending to the Prussian-German military honor code’s mixed messages...

Modal logic S5 is commonly viewed as an epistemic logic that captures the most basic properties of knowledge. Kripke proved a completeness theorem for the first-order modal logic S5 with respect to a possible worlds semantics. A multiagent version of...

Beginning the 1960s, police forces in the United States underwent a transformation. In response to the civil unrest taking place in cities across the country, public support for increased federal funding for law enforcement soared. With this increased funding, police...

Although first proposed in the database theory as properties of functional dependencies between attributes, Armstrong's axioms capture general principles of information flow by describing properties of dependencies between sets of pieces of information. This article generalizes Armstrong's axioms to a...

The article investigates an influence relation between two sets of agents in a social network. It proposes a logical system that captures propositional properties of this relation valid in all threshold models of social networks with the same structure. The...

The fact that a coalition has a strategy does not mean that the coalition knows what the strategy is. If the coalition knows the strategy, then such a strategy is called a know-how strategy of the coalition. The paper proposes...

The paper proposes a bimodal logic that describes an interplay between distributed knowledge modality and coalition know-how modality. Unlike other similar systems, the one proposed here assumes perfect recall by all agents. Perfect recall is captured in the system by...

This article examines a famous 1906 event that occurred when a con man dressed in a captain's uniform commandeered two small contingents of soldiers in Berlin and took them to nearby Köpenick, where he proceeded to arrest the city’s mayor...

In light of Wilhelm II’s well-known predilection for military uniforms and displays, many of his contemporaries regarded him as a real-life version of the titular figure in Hans Christian Andersen’s fable “The Emperor’s New Clothes.” This essay uses the concept...

The existence of a coalition strategy to achieve a goal does not necessarily mean that the coalition has enough information to know how to follow the strategy. Neither does it mean that the coalition knows that such a strategy exists...
