Probabilistic Effectivity in the Subspace Theorem and the Distribution of Algebraic Projective Points

Abstract: The celebrated Roth’s theorem in Diophantine Approximation determines the degree to which an algebraic number may be approximated by rationals. A corollary of this theorem yields a transcendence criterion for real numbers based off of their decimal expansion. This theorem, and its broad generalisation due to Schmidt, famously suffers from ineffectivity. This motivates one to address this issue in the probabilistic context, whereby one makes progress in the direction of effectivity in an appropriately defined probabilistic regime. From this analysis is derived an analogue of Khintchine's theorem for algebraic numbers, answering a question of Beresnevich, Bernick, and Dodson on a density version of Waldschmidt’s conjecture.
