Central Configurations and Mutual Differences [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2017 Central configurations are solutions of the equations $λm_j\boldsymbol{q}_j = \frac{\partial U}{\partial \boldsymbol{q}_j}$, where $U$ denotes the potential function and each $\boldsymbol{q}_j$ is a point in the $d$-dimensional Euclidean space $E\cong {\mathbb R}^d$, for $j=1,\ldots, n$.

Planar Central Configurations of Symmetric Five-Body Problems with Two Pairs of Equal Masses
Advances in Astronomy, 2016 We study central configuration of a set of symmetric planar five-body problems where (1) the five masses are arranged in such a way that m1, m2, and m4 are collinear and m2, m3, and m5 are collinear; the two sets of collinear masses form a triangle with ...

Centrally Symmetric Configurations of Integer Matrices [PDF]
Nagoya Mathematical Journal, 2014 Abstract The concept of centrally symmetric configurations of integer matrices is introduced. We study the problem when the toric ring of a centrally symmetric configuration is normal and when it is Gorenstein. In addition, Gröbner bases of toric ideals of centrally symmetric configurations are discussed.
