Explicit Poincaré duality in the cohomology ring of the SU(2) character variety of a surface
Lisa Jeffrey, Aidan Lindberg, Steven Rayan
We provide an explicit description of the Poincaré dual of each generator of the rational cohomology ring of the character variety for a genus surface with central exte…

Geodesics on a Kerr-Newman-(anti-)de Sitter instanton
Aidan Lindberg, Steven Rayan
We study geodesics along a noncompact Kerr-Newman instanton, where the asymptotic geometry is either de Sitter or anti-de Sitter. We use first integrals for the Hamilton-Jacobi equ…
