  • Summary

    This chapter briefly recapitulates the main findings of the book. In addition, it provides a discussion whether major current developments – such as climate change – make modifications in constitutional emergency provisions necessary. It also discusses the relationship between independent agencies (such as central banks) and emergency provisions. Finally, it asks how resilience can be improved.

  • Ramsey’s theorem states that for any coloring of the n-element subsets of ℕ with finitely many colors, there is an infinite set H such that all n-element subsets of H have the same color. The strength of consequences of Ramsey’s theorem has been extensively studied in reverse mathematics and under various reducibilities, namely, computable reducibility and uniform reducibility. Our understanding of the combinatorics of Ramsey’s theorem and its consequences has been greatly improved over the past decades. In this paper, we state some questions which naturally arose during this study. The inability to answer those questions reveals some gaps in our understanding of the combinatorics of Ramsey’s theorem.
