Query: Analytic solutions of the geodesic equation for U(1)^2 dyonic rotating
  black holes   In this article we derive the geodesic equations in the $\text{U(1)}^2$
dyonic rotating black hole spacetime. We present their solutions in terms of
the Kleinian $\sigma$-function and in special cases in terms of the
Weierstra{\ss} $\wp$-, $\sigma$- and $\zeta$-functions. To give a list of all
possible orbits, we analyse the geodesic motion of test particles and light
using parametric diagrams and effective potentials.
