Continuum Eigenmodes in Some Linear Stellar Models
Christopher J. Winfield
We apply parallel approaches in the study of continuous spectra to adiabatic stellar models. We seek continuum eigenmodes for the LAWE formulated as both finite difference and line…
Well-posedness of Einstein's Equation with Redshift Data
Christopher Winfield
We study the solvability of a system of ordinary differential equations derived from null geodesics of the LTB metric with data given in terms of a so-called redshift parameter. Da…
Asymptotic Methods of ODEs: Exploring Singularities of the Second Kind
Christopher J. Winfield
We develop symbolic methods of asymptotic approximations for solutions of linear ordinary differential equations and use to them stabilize numerical calculations. Our method follow…
Local Solvability on H_1: Non-homogeneous Operators
Christopher J. Winfield
Local solvability and non-solvability are classified for left-invariant differential operators on the Heisenberg group H_1 of the form L=P_n(X,Y)+Q(X,Y) where the P_n are certain h…
