Spectral edge behavior for eventually monotone Jacobi and Verblunsky coefficients
Milivoje Lukic
We consider Jacobi matrices with eventually increasing sequences of diagonal and off-diagonal Jacobi parameters. We describe the asymptotic behavior of the subordinate solution at…

bounded variation and absolutely continuous spectrum of Jacobi matrices
Yoram Last, Milivoje Lukic
We disprove a conjecture of Breuer-Last-Simon concerning the absolutely continuous spectrum of Jacobi matrices with coefficients that obey an bounded variation condition w…
