Description

We employ the so-called companion matrix method from computational algebraic geometry, tailored for zero-dimensional ideals, to study the scattering equations. The method renders the CHY-integrand of scattering amplitudes computable using simple linear algebra and is amenable to an algorithmic approach. Certain identities in the amplitudes as well as rationality of the final integrand become immediate in this formalism.

Translated Description (Arabic)

نحن نستخدم ما يسمى طريقة المصفوفة المصاحبة من الهندسة الجبرية الحسابية، المصممة للمثل العليا الصفرية الأبعاد، لدراسة معادلات التشتت. تجعل الطريقة تكامل CHY لمعدلات سعة التشتت قابلة للحساب باستخدام الجبر الخطي البسيط وقابلة للنهج الخوارزمي. تصبح بعض الهويات في السعات وكذلك عقلانية التكامل النهائي فورية في هذه الشكلية.

Translated Description (French)

Nous utilisons la méthode dite de la matrice compagnon à partir de la géométrie algébrique computationnelle, adaptée aux idéaux de dimension zéro, pour étudier les équations de diffusion. Le procédé rend l'intégrande CHY des amplitudes de diffusion calculables à l'aide d'une algèbre linéaire simple et se prête à une approche algorithmique. Certaines identités dans les amplitudes ainsi que la rationalité de l'intégrand final deviennent immédiates dans ce formalisme.

Translated Description (Spanish)

Empleamos el llamado método de matriz compañera de la geometría algebraica computacional, adaptada a ideales de dimensión cero, para estudiar las ecuaciones de dispersión. El método hace que el integrando CHY de amplitudes de dispersión sea computable utilizando un álgebra lineal simple y es susceptible de un enfoque algorítmico. Ciertas identidades en las amplitudes, así como la racionalidad del integrando final, se vuelven inmediatas en este formalismo.
