Inversions and the Gog-Magog problem
Philippe Biane, Hayat Cheballah
We consider the problem of finding a bijection between the sets of alternating sign matrices and of totally symmetric self complementary plane partitions, which can be reformulated…
Combinatorial Hopf algebra structure on packed square matrices
Hayat Cheballah, Samuele Giraudo, Rémi Maurice
We construct a new bigraded Hopf algebra whose bases are indexed by square matrices with entries in the alphabet , , without null rows or columns. This…
Gog, Magog and Schützenberger II: Left trapezoids
Philippe Biane, Hayat Cheballah
We are interested in finding an explicit bijection between two families of combinatorial objects: Gog and Magog triangles. These two families are particular classes of Gelfand-Tset…
Gog and Magog triangles, and the Schutzenberger involution
Hayat Cheballah, Philippe Biane
We describe an approach to finding a bijection between Alternating Sign Matrices and Totally Symmetric Self-Complementary Plane Partitions, which is based on the Schutzenberger inv…
