N2 - For continuous and discrete one-dimensional Schrödinger operators with square summable potentials, the absolutely continuous part of the spectrum is essentially supported by [0, ∞) and [-2, 2] respectively. This fact is proved by considering a priori estimates for the transmission coefficient.
