Abstract
We present some necessary and/or sufficient conditions for the positivity problem of three-term recurrence sequences. As applications, we show the positivity of some diagonal Taylor coefficients of some rational functions in a unified approach. We also establish a criterion for the positivity and log-convexity of such sequences.
