General Duffin--Schaeffer-type counterexamples in diophantine approximation
Sam Chow, Manuel Hauke, Andrew Pollington +1
Duffin and Schaeffer provided a famous counterexample to show that Khintchine's theorem fails without monotonicity assumption. Given any monotonically decreasing approximation func…
