N2 - We consider the set Ω2 of double zeros in (0, 1) for power series with coefficients in (−1, 0, 1). We prove that Ω2 is disconnected, and estimate minΩ2 with high accuracy. We also show that [2−1/2 − η, 1) ⊂ Ω2 for some small, but explicit, η > 0 (this was known only for η = 0). These results have applications in the study of infinite Bernoulli convolutions and connectedness properties of self-affine fractals.
