Feb 26, 2020 at 21:57 comment added Iosif Pinelis You are right, a sentence like this, "$\sum A_i/K$ converges as $K\to\infty$ to $-\sum D_i^{T}V_{i}^{-1}D_i/K$", cannot possibly have a meaning. Perhaps, the authors meant here someting like this: "$\sum A_i/K+\sum D_i^{T}V_{i}^{-1}D_i/K\to0$ as $K\to\infty$".
