It is shown to provide a convenient parametrization for many important physical systems. As an example, the kinematics of a rotating rigi...

Using the isomorphism between $\mathrm{SU}(1,1...  作者：Danail S. Brezov , Clementina D. Mladenova , Ivaïlo M.

Although not always providing the most efficient solution, the method allows for avoiding gimbal lock singularities and decouples the dependence on ...  作者：Veliko D. Donchev , Clementina D.

Here we present results based on a program package for building the generating matrices of the irreduc...
