This community is dedicated to the development and discussion of Relational Change (RC) as a foundational axiom underlying matter, spacetime, computation, and systems. RC is approached as a pre-empirical and pre-theoretical construct, formulated at the intersection of contemporary philosophy, mathematics, and mathematical physics. The aim is to provide a rigorous conceptual and formal framework from which physical, computational, and systemic structures may be derived or interpreted. The community welcomes works that advance axiomatic clarity, formal structure, or critical analysis of relational foundations, while maintaining a clear distinction between foundational theory and domain-specific applications.
