Brehm-Wintner-Conley Dimension, Plücker Coordinates, and Generalized Dziobek-Williams Equations for Central Configurations

Thiago Dias

We develop an algebraic framework for central configurations of the $n$ -body problem with homogeneous potentials, grounded in the exterior algebra of the configuration space and th…

Generalized Laura-Andoyer equations and the enumeration of some symmetrical classes of Dziobek configurations

Thiago Dias, Ya-Lun Tsai

We study the symmetrical Dziobek configurations where, in $R^{d}$ , there are $d$ bodies with unit masses at the vertices of a regular $(d - 1)$ -dimensional simplex of unit e…

The Veronese Geometry of Dziobek Configurations and Generic Finiteness for Homogeneous Potentials

Thiago Dias

The main contribution of this paper is the proof of the generic finiteness of Dziobek central configurations for a homogeneous potential and the derivation of a uniform upper bound…

Counting square free monomial cremona maps

Bárbara Costa, Thiago Dias, Rodrigo Gondim +1

We give a complete list of square-free Cremona maps with at most six variables, up to equivalence classes. We also build an algorithm to count monomial square-free Cremona transfor…

Waring problems and the Lefschetz properties

Thiago Dias, Rodrigo Gondim

We study three variations of the Waring problem for polynomials, concerning the Waring rank, the border rank and the cactus rank of a form and we show how the Lefschetz properties…

Generic finiteness for a class of symmetric planar central configurations of the six-body problem and the six-vortex problem

Thiago Dias, Bo-Yu Pan

A symmetric planar central configuration of the Newtonian six-body problem $x$ is called cross central configuration if there are precisely four bodies on a symmetry line of $x$ . W…

Counting Square free Cremona monomial maps

Barbara Costa, Thiago Dias, Rodrigo Gondim

We use combinatorics tools to reobtain the classification of monomial quadratic Cremona transformations in any number of variables given in \cite{SV2} and to classify and count squ…

New equations for central configurations and generic finiteness

Thiago Dias

We consider the finiteness problem for central configurations of the $n -$ body problem. We prove that, for $n \geq 4$ , there exists a (Zariski) closed subset $B$ in the mass space $\m…
