Title: Edit Distance in l1: Matching Bounds up to Constants in the Exponent.

Abstract: We determine the exponential scale of the least ℓ1 distortion of unit-cost edit distance on all strings of length at most d. For every sufficiently large d, uniformly over finite alphabets of size at least two, the distortion lies between ${}exp(c{}sqrt{{}log d{},{}log{}log d})$ and ${}exp(C{}sqrt{{}log d{},{}log{}log d})$ for absolute constants $c,C{}gt 0$. The lower bound already holds on binary strings of one common length. Thus the order of logarithmic distortion is sharp up to absolute constants.

This abstract is a catalogue record. It is not a verification and not a premise. It does not close O.1. O.1 stays NOT_CLOSED. No quantum coefficient is admitted. No compilation is asserted.
