Bari-Markus property for Riesz projections of Hill operators with singular potentials

Plamen Djakov, Boris Mityagin

The Hill operators $L y = - y^{''} + v (x) y, x \in [0, π],$ with $H^{- 1}$ periodic potentials, considered with periodic, antiperiodic or Dirichlet boundary conditions, ha…

Deviations of Riesz projections of Hill operators with singular potentials

Plamen Djakov, Boris Mityagin

It is shown that the deviations $P_{n} - P_{n}^{0}$ of Riesz projections $P_{n} = \frac{1}{2 π i} \int_{C_{n}} (z - L)^{- 1} d z, C_{n} = {∣ z - n^{2} ∣ = n},$ of Hill operators $L y = - y^{\prime…
