Regularity of the D-bar-Neumann Operator, the Bergman Projection and the Canonical Solution Operator of D-bar-Equation
… this thesis by a brief introduction to the $\bar{\partial}$-problem in several complex variables and the classical $L^2$ Theorem of $\bar{\partial}$. We then introduce the $\bar{\partial}$-Neumann operator on pseudoconvex domains and give a description of the relation between the …

d-bar continuity beyond subshifts of finite type
The main result of this thesis is that for a mixing countable state Markov shift, the map taking a strongly positive recurrent potential to its Ruelle-Perron-Frobenius (RPF) measure is continuous in the $\overline{d}$-metric on the space of measures and the metric coming from the Hölder norm on the …

A direct D-bar reconstruction algorithm for complex admittivities in W2,∞(Ω) for the 2-D EIT problem
… proof that was the first approach using D-bar methods to solve the full nonlinear problem for twice-differentiable conductivities and permittivities. In this thesis the necessary formulas to turn her proof into a direct D-bar reconstruction algorithm that solves the full nonlinear …

Probing the flavor dependence of proton's light-quark sea in the SeaQuest experiment at Fermilab
… experiments. The Bjorken-$x$ dependence of the $\bar{d}/\bar{u}$ ratio extracted from the Fermilab E866 experiment also revealed an intriguing drop at the highest values of $x$. The Fermilab E906/SeaQuest experiment was designed to measure $\bar{d}/\bar{u}$ with improved accuracy at high …

An approximation method for electrical impedance tomography
… a linearized inverse problem (d) solving a d-bar equation, and (e) scaling the resulting image based on analytical results for a disc. In the development of the approximation, a new formula for Fadeev's Green's function is presented in terms of the Exponential Integral function. Also, new …

Theory and applications of a functional from metric geometry
… x-y\vert\sp\alpha\ d\mu(x)d\bar \nu(y)$. Study of the energy integral $J\sp\alpha$ has its roots in metric embedding theory and potential theory. Subject to certain moment vanishing conditions, a representation formula is proved using the Fourier transform and tempered …

Measurement of high-mass dimuon production for p+p and p+d collisions with 120 GeV proton beam at Fermilab
… allow the measurement of sea quark asymmetry, $\bar{d}/\bar{u}$, for Bjorken-{\it x} ranging from 0.1 to 0.45, extending the measurements of the previous experiment NuSea/E866. Improved statistics expected at SeaQuest for ${\it x}>0.25$ will allow us to check the surprising behaviour of …

Integrable Evolution Partial Differential Equations: Multidimensions and Dirichlet-to-Neumann Maps
… = t₂= 0, can be solved by means of a nonlocal d-bar problem. Here we treat the multidimensional generalisations of the DS system and of the three-wave interaction equations. Starting from these equations in 2+1 dimensions (x, y and t), we construct their generalisations in 4+2 dimensions by …
