Kovalevskaya Top
Encyclopedia
The Kovalevskaya Top is one of a brief list of known examples of integrable rigid body motion . It was discovered by Sofia Kovalevskaya
in 1888 and presented in her paper 'Sur Le Probleme De La Rotation D'Un Corps Solide Autour
D'Un Point Fixe' .
It is defined as a top
in which two of the principal moments of inertia are twice that of the third and the center of mass
is in the plane of the two equal moments of inertia.

Top (mathematics)
In the context of a module M over a ring R, the top of M is the largest semisimple quotient module of M if it exists.For finite-dimensional k-algebras , if rad denotes the intersection of all proper maximal submodules of M , then the top of M is M/rad...

Center of mass
In physics, the center of mass or barycenter of a system is the average location of all of its mass. In the case of a rigid body, the position of the center of mass is fixed in relation to the body...
