Statement

Strict admissibility is defined on the Theorem 1 page.

Theorem 3 (p. 629). Let {ξn}n=1∞\{\xi_n\}_{n=1}^\infty be a sequence of independent random variables, each uniformly distributed on (0,1)(0,1). Then:

  1. there is a constant c>0c>0 such that if q>1q>1 and λ>cq3\lambda>cq^3, the sequence {(n+λ−1)q/ξn}\{(n+\lambda-1)^q/\xi_n\} is strictly admissible with probability greater than 1/21/2;
  2. there is a constant ν0>1\nu_0>1 such that for every ν∈(1,ν0]\nu\in(1,\nu_0] the sequence {ν(n−1)1/3/ξn}\{\nu^{(n-1)^{1/3}}/\xi_n\} is strictly admissible with probability greater than 1/21/2.

Read depth. Claims checked: the statement was read clause by clause on the printed page. The note prints no proofs.

Proof pointer

None in the note. The note says (p. 629) that either part gives the upper bound of Theorem 4.

Dependencies

None stated.
