Deciding Cuspidality of Manipulators through Computer Algebra and Algorithms in Real Algebraic Geometry [PDF]

International Symposium on Symbolic and Algebraic Computation, 2022
Cuspidal robots are robots with at least two inverse kinematic solutions that can be connected by a singularity-free path. Deciding the cuspidality of generic 3R robots has been studied in the past, but extending the study to six-degree-of-freedom robots

Exact spin correlators of integrable quantum circuits from algebraic geometry

SciPost Physics
We calculate the correlation functions of strings of spin operators for integrable quantum circuits exactly. These observables can be used for the calibration of quantum simulation platforms.

Enumerative real algebraic geometry [PDF]

Algorithmic and Quantitative Aspects of Real Algebraic Geometry in Mathematics and Computer Science, 2003
Enumerative Geometry is concerned with the number of solutions to a structured system of polynomial equations, when the structure comes from geometry. Enumerative real algebraic geometry studies real solutions to such systems, particularly a priori information on their number. Recent results in this area have, often as not, uncovered new and unexpected

Geometry of tropical curves and application to real algebraic geometry

, 2014
Dans cette thèse, on s'intéresse aux questions d'approximabilité des courbes complexes tropicales par des familles de courbes algébriques complexes. La motivation de telles questions provient de la correspondance étroite entre géométries algébriques et tropicales des courbes planaires et de ses applications en géométrie énumérative et en géométrie ...

Real algebraic geometry for matrices over commutative rings [PDF]

, 2012
We define and study preorderings and orderings on rings of the form $M_n(R)$ where $R$ is a commutative unital ring. We extend the Artin-Lang theorem and Krivine-Stengle Stellens\"atze (both abstract and geometric) from $R$ to $M_n(R)$.
