On the closed range problem for composition operators on the Dirichlet space
Concrete Operators, 2019 We characterize closed range composition operators on the Dirichlet space for a particular class of composition symbols. The characterization relies on a result about Fredholm Toeplitz operators with BMO1 symbols, and with Berezin transforms of vanishing

Estimates by gap potentials of free homotopy decompositions of critical Sobolev maps
Advances in Nonlinear Analysis, 2019 A free homotopy decomposition of any continuous map from a compact Riemannian manifold đ to a compact Riemannian manifold đ into a finite number maps belonging to a finite set is constructed, in such a way that the number of maps in this free homotopy ...

I: Retrieval of Atmospheric Carbon Dioxide from High-Resolution Spectra. II: Interannual Variability of the Stratospheric Quasi-Biennual Oscillation [PDF]
, 2011 This thesis is devoted to an understanding of climate changes in the troposphere and the stratosphere from different aspects. In the troposphere, projecting future climate depends on our understanding of the exchange of COâ between the atmosphere, oceans,

Geometric Inequalities and Bounded Mean Oscillation [PDF]
, 2020 In this thesis, we study the space of functions of bounded mean oscillation (BMO) on shapes. We prove the boundedness of important nonlinear operators, such as maximal functions and rearrangements, on this space and analyse how the bounds are affected by

Two-dimensional magnetohydrodynamic turbulence in the limits of infinite and vanishing magnetic Prandtl number [PDF]
, 2013 LAKB was supported by an EPSRC post-graduate studentship.We study both theoretically and numerically two-dimensional magnetohydrodynamic turbulence at infinite and zero magnetic Prandtl number $Pm$ (and the limits thereof), with an emphasis on solution ...

What can a mean-field model tell us about the dynamics of the cortex? [PDF]
, 2010 In this chapter we examine the dynamical behavior of a spatially homogeneous two-dimensional model of the cortex that incorporates membrane potential, synaptic flux rates and long- and short-range synaptic input, in two spatial dimensions, using ...

Local vanishing mean oscillation
, 2022 We consider various notions of vanishing mean oscillation on a (possibly unbounded) domain $\Omega \subset \mathbb{R}^n$, and prove an analogue of Sarason's theorem, giving sufficient conditions for the density of bounded Lipschitz functions in the ...

Fractional maximal functions and mean oscillation on bounded doubling metric measure spaces [PDF]
, 2023 Let $(X,d,\mu)$ be a doubling metric measure space. We consider the behaviour of the fractional maximal function $M^\alpha$ for $0\leq \alpha0$, we additionally assume that the space is bounded.

Advanced Functional Materials, EarlyView.Here, we provide the reader with the current state of the art in the fabrication of highâT2âcoherence diamond, optimized through the use of double electronâelectron resonance (DEER) spectroscopy. We reveal the main as well as yet unidentified spin defects, the reduction of which is essential for reducing the spin bath and fabricating materials for ...
