The Collatz Conjecture asserts that every integer, when iterated under a function taking odd $n$ to $3n+1$ and even $n$ to $\frac{n}2$, will eventually reach $1$. The questions around the conjecture are questions about the status of the $3n+1$ problem or that of its generalizations and about literature. Since it is an exponential diophantine problem which is iterated according to residues $\pmod 2$, such questions often deal with modular arithmetic and subsequent problems. Also the general problem of approximation of powers of 2 to that of powers of 3 (in the original $3n+1$-formulation) occurs as determining ingredient.
