WebAbstract. We introduce a method to obtain the envelopes of eccentric orbits in vacuum axially symmetric potentials, Φ ( R, z), endowed with z -symmetry of reflection, as it is usual in discoidal galaxies and other spheroidal-shaped astrophysical objects. By making the transformation z → a + a 2 + z 2, with a > 0, we compute the resulting ...

WebEinstein introduced a convention whereby if a particular suﬃx (e.g., i) appears twice in a single term of an expression then it is implicitly summed. For example, in traditional notation x.y = x 1y 1+x 2y 2+x 3y 3= X3 i=1 x iy i; using summation convention we simply write x.y = x iy i. All we are doing is not bothering to write down the P !
