Generic Finiteness of (n-2)-dimensional Central Configurations for Homogeneous Potentials with Integer Exponents (II)
Thiago Dias Oliveira Silva (National Tsing Hua University)
Abstract:
We will continue our talk from last week. We present a polynomial parametrization for central configurations of dimension n-k. Also, we give a criterion for the dimension of an arbitrary central configuration in terms of the Cayley-Menger determinant. Finally, by using the Jacobian Criterion from Algebraic Geometry, we prove generic finiteness with respect to the masses for (n-2)-dimensional central configurations in the n-body problem under homogeneous potentials with integer exponents.
