Logarithmic quasi-stationary extinction-rate conjecture

From papers

Let λN\lambda_N be the quasi-stationary eigenvalue of the interior transition matrix, and let α\alpha be the parameter from Theorem~. Assume the conditions of Theorem~.

Logarithmic extinction-rate conjecture.

limN1Nlog(1λN)=α.\lim_{N\to\infty}\frac{1}{N}\log(1-\lambda_N)=\alpha.

This is presented as a weak form of the conjectured sharp asymptotic relation αN/(1λN)1\alpha^N/(1-\lambda_N)\to1. It gives only the exponential scale of the quasi-stationary extinction probability and is not proved in the paper.
