We apply the Thom-Milnor theorem to obtain upper bounds on the amount of critical points in various problems, including Maxwell's problem on point charges, SINR, potential generated by fixed Newtonian point masses with a quadratic term, and central configurations in the n-body problem.
We apply the Thom-Milnor theorem to obtain the upper bounds on the amount of isolated (1) critical points of a potential generated by several fixed point charges(Maxwell's problem on point charges), (2) critical points of SINR, (3) critical points of a potential generated by several fixed Newtonian point masses augmented with a quadratic term, (4) central configurations in the n-body problem. In particular, we get an exponential bound for Maxwell's problem and the polynomial bound for the case of an even dimensional potential in Maxwell's problem.
