Shadow Sequences of Integers

Explore the concept of shadow sequences of integers in this 39-minute lecture by Valentin Ovsienko from the Centre national de la recherche scientifique (CNRS) and University of Reims. Delve into topics such as cluster algebras, cluster super algebra, coordinate transformations, and anticommute G2M. Examine hypergraphs, special cases, and the underlying idea behind shadow sequences. Gain insights into dual numbers and study various examples to deepen your understanding of this mathematical concept. This talk is part of the Workshop on Supergeometry and Bracket Structures in Mathematics and Physics organized by the Fields Institute.
