			<li>[[User:Tohline/2DStructure/TCsimplification#Common_Theme:_Determining_the_Gravitational_Potential_for_Axisymmetric_Mass_Distributions\|Using Toroidal Coordinates to Determine the Gravitational Potential of Axisymmetric Systems]]:  This page summarizes, and provides links to, several of my favorite chapters. Most significantly, it highlights the overlap that exists between Howard Cohl's dissertation research (remember that Howie was an IU undergraduate astronomy major) and Wong's (1973) fabulous, but little appreciated, analytic derivation of the gravitational potential both inside and outside of a uniform-density, circular torus.</li>
