The complete set of solutions of the geodesic equations in the space-time of a Schwarzschild black hole pierced by a cosmic string [PDF]
, 2009 We study the geodesic equation in the space-time of a Schwarzschild black hole pierced by an infinitely thin cosmic string and give the complete set of analytical solutions of this equation for massive and massless particles, respectively.

Transient Antiskyrmion‐Mediated Topological Transitions in Isotropic Magnets
Advanced Science, EarlyView.A transient antiskyrmion‐mediated pathway that drives repeated stripe‐to‐skyrmion transitions is revealed, producing a net increase in topological charge in isotropic Dzyaloshinskii–Moriya interaction films. Experiments and simulations identify the antiskyrmion as a metastable excitation, enabling stochastic bitstream generation for probabilistic ...

Pseudoriemannian metrics on spaces of bilinear structures
, 1991 The space of all non degenerate bilinear structures on a manifold $M$ carries a one parameter family of pseudo Riemannian metrics. We determine the geodesic equation, covariant derivative, curvature, and we solve the geodesic equation explicitly.

Analytic solutions of the geodesic equation in axially symmetric space-times [PDF]
, 2009 The complete sets of analytic solutions of the geodesic equation in Taub-NUT-(anti-) de Sitter, Kerr-(anti-)de Sitter and also in general Plebański-Demiański space-times without acceleration are presented. The solutions are given in terms of the Kleinian

Orthospectra of geodesic laminations and dilogarithm identities on moduli space [PDF]
, 2009 .We define the function LW T1.S/!S by letting L.v/D Length..v// . We note that L.v/ is measurable but can be infinite. We define measure M on the real line by M D L . Then M is a measure describing the distribution of the lengths of .v/ . We cut S along
