Kripke's Reduction of Löb's Theorem to the Second Incompleteness Theorem

open access: yesTheoria, EarlyView.
ABSTRACT In this paper, we discuss Kripke's reduction of Löb's Principle to the Second Incompleteness Theorem. We have a closer look at the non‐constructive character of the reduction. We reflect on what the argument has to tell us. In the Appendix, We give a strengthening of Löb's Principle suggested by Kripke's reduction.

open access: yesTheoria, EarlyView.
ABSTRACT ‘Spectrum arguments’ or ‘continuum arguments’ in moral philosophy are sometimes invalid because they commit a particular fallacy I call the ‘Continuum Fallacy’.

Chebotarev's theorem for cyclic groups of order pq$pq$ and an uncertainty principle

open access: yesBulletin of the London Mathematical Society, EarlyView.
Abstract Let p$p$ be a prime number and ζp$\zeta _p$ a primitive p$p$th root of unity. Chebotarev's theorem states that every square submatrix of the p×p$p \times p$ matrix (ζpij)i,j=0p−1$(\zeta _p^{ij})_{i,j=0}^{p-1}$ is nonsingular. In this paper, we prove the same for principal submatrices of (ζnij)i,j=0n−1$(\zeta _n^{ij})_{i,j=0}^{n-1}$, when n=pr ...
