On spectral measures and convergence rates in von Neumann's Ergodic Theorem

M. Aloisio, S. L. Carvalho, C. R. de Oliveira +1

We show that the power-law decay exponents in von Neumann's Ergodic Theorem (for discrete systems) are the pointwise scaling exponents of a spectral measure at the spectral value~$…

Exponential dichotomy for dynamically defined matrix-valued Jacobi operators

Silas L. Carvalho, Fabricio Vieira

We present in this work a proof of the exponential dichotomy for dynamically defined matrix-valued Jacobi operators in $(C^{l})^{Z}$ , given for each $ω \in Ω$ by t…
