Lissajous curve
A Lissajous curve , also known as Lissajous figure or Bowditch curve , is the graph of a system of parametric equations
: x=A\sin(at+\delta),\quad y=B\sin(bt),
which describe the superposition of two perpendicular oscillations in x and y dire ...
(or figure, or spiral), a mathematical figure showing a type of harmonic motion

Lissajous knot
In knot theory, a Lissajous knot is a knot defined by parametric equations of the form
:x = \cos(n_x t + \phi_x),\qquad y = \cos(n_y t + \phi_y), \qquad z = \cos(n_z t + \phi_z),
where n_x, n_y, and n_z are integers and the phase shifts \phi_ ...

Lissajous orbit
In orbital mechanics, a Lissajous orbit (), named after Jules Antoine Lissajous, is a quasi-periodic orbital trajectory that an object can follow around a Lagrangian point of a three-body system without requiring any propulsion. Lyapunov orbits ...
