Stable invariant subspaces, reflexivity, and BMO
… in which functions of bounded mean oscillation (BMO) and vanishing mean oscillation (VMO) can be studied. In this setting we prove a version of the John-Nirenberg theorem and a version of Sarason's characterization of VMO as the closure of the uniformly continuous functions in BMO. We also prove …

The Convergence of Lebesgue Derivatives and Ergodic Averages
… to prove that these operators map Linfinity to BMO and are of strong type (p, p) where 1 < p < infinity for the case that the stochastic processes are Lebesgue differentiation or ergodic averages. In Chapter 2, we prove the appropriate sublinear operator interpolation between the weak type (1, …

Lamina Cribrosa and Optic Nerve Head Geometry as a Function of Myopia in Older Normal Eyes
… program to calculate Bruch’s Membrane Opening (BMO) area and circumference, mean anterior lamina cribrosa surface depth (ALCSD), mean minimum rim width (MRW) and mean scaled MRW. Results: Refractive errors and axial lengths (ALs) in highly myopic eyes (mean SE = -7.18 ± 1.17 D; mean AL = 26.41 ± …

Weighted estimates for dyadic operators with complexity
… dual paraproduct associated to a function $b\\in BMO$, depends linearly on the $A_2$-characteristic of the weight $w$, linearly on the $BMO$-norm of $b$, and polynomially in the complexity. Moreover we prove that the $L^2(w)$-norm of the composition of these operators depends linearly on the …

Articles on Potential Theory, Functional Analysis and Hankel Forms
… mean oscillation, it is well known that VMO** = BMO and there are many characterizations of the distance from a function f in BMO to VMO. When considering the Bloch space, results in the same vein are available with respect to the little Bloch space. In this paper such duality results and …

New Directions in Bandit Learning: Singularities and Random Walk Feedback
… bandit learning for Bounded Mean Oscillation (BMO) functions, where the goal is to ``maximize'' a function that may go to infinity in parts of the space. For an unknown BMO function, I will present algorithms that efficiently finds regions with high function values. To handle possible …

Commutators and dyadic paraproducts on weighted Lebesgue spaces
… Hilbert, Riesz and Beurling transforms with a BMO function b depends quadratically on the A2 characteristic of the weight, as opposed to the linear dependence known to hold for the operators themselves. It is known that the operator norms of these commutators can be controlled by the norm of …

Essays on Commodity Price Shocks, Bank Risk and Market Volatility Forecasting
… loan (NPL) ratios of Bank of Montreal (BMO) and Canadian Imperial Bank of Commerce (CIBC) at 2010Q2 and 2010Q3, respectively. For BMO and CIBC, the banking factors contribute the most to the peaks of the Value at Risk (VaR) forecasts of the NPL ratios. The commodity price factors also …

Chord arc submanifolds of arbitrary codimension
… Ahlfors regularity condition, if and only if the BMO-norm of the normal spaces is small and the submanifolds satisfies a Reifenberg flatness condition with a small constant. The main tool hereby is that such submanifolds contain big portions of the graph of continuous differentiable functions. …

Structural and Electromagnetic Study of Heavily Doped ZR-Added REBCO Coated Conductors Fabricated by Reel-To-Reel MOCVD
… and density. The incorporation of a high BaMO3 (BMO; M=Zr, Hf, Sn) dopant concentration in REBCO films to achieve a higher density of nanoscale defects has been demonstrated in this work as a very effective strategy to pin the vortices, especially in moderate-to-high applied magnetic fields and …

Sparse technology in weighted harmonic analysis
… integral operators and their commutators with BMO functions. We also prove a maximal function control theorem for these operators, that is, we prove that the weighted $L^p$ norm is bounded by the weighted $L^p$ norm of a natural maximal operator when the weight belongs to $A_\infty$. The heart …
