Representation theorems for actual and alpha powers over general concurrent game frames without assuming independence of agents

Zixuan Chen, Fengkui Ju, Thomas Agotnes

Concurrent game frames are a standard semantic framework for logics of strategic reasoning. Two notions of coalition power can be derived from such frames: alpha powers and actual…

Representation theorems for actual and alpha powers over two-agent general concurrent game frames

Zixuan Chen, Fengkui Ju, Thomas Agotnes

One of the most well-known connections between modal logic and games is Pauly's representation theorem: that the induced powers of individuals and coalitions in a concurrent game f…

Seven kinds of equivalent models for generalized coalition logics

Zixuan Chen, Fengkui Ju

Coalition Logic is an important logic in logical research on strategic reasoning. In two recent papers, Li and Ju argued that generally, concurrent game models, models of Coalition…

Completeness of coalition logics with seriality, independence of agents, or determinism

Yinfeng Li, Fengkui Ju

Coalition Logic is a central logic in logical research on strategic reasoning. In a recent paper, Li and Ju argued that generally, models of Coalition Logic, concurrent game models…

A minimal coalition logic

Yinfeng Li, Fengkui Ju

Coalition Logic is an important logic in logical studies of strategic reasoning, whose models are concurrent game models. In this paper, first, we systematically discuss three assu…

Completeness of two fragments of a logic for conditional strategic reasoning

Yinfeng Li, Fengkui Ju

Classical logics for strategic reasoning, such as Coalition Logic and Alternating-time Temporal Logic, formalize absolute strategic reasoning about the unconditional strategic abil…
