Vd. Ivashchuk et Vn. Melnikov, MULTITEMPORAL GENERALIZATION OF THE SCHWARZSCHILD SOLUTION, International journal of modern physics D, 4(2), 1995, pp. 167-173
The n-time generalization of the Schwarzschild solution is considered.
The equations of geodesics for the metric are integrated. The multite
mporal analogues of Newton's laws for the extended objects described b
y the solution are suggested. The scalar-vacuum generalization of the
solution is also presented.
