From quasi- +‎ geodesic.

quasigeodesic (not comparable)

1. (mathematics) Of a map ${\displaystyle f:{\textbf {R}}\to Y}$, having constants ${\displaystyle K>0}$ and ${\displaystyle C\geq 0}$ such that ${\displaystyle {1 \over K}d(x,y)-C\leq d(f(x),f(y))\leq Kd(x,y)+C.}$

     We prove Calegari's conjecture that every quasigeodesic flow on a closed hyperbolic 3-manifold has closed orbits..
