Some combinatorial interpretations of the Macdonald identities for affine root systems and Nekrasov--Okounkov type formulas
David Wahiche
We explore some connections between vectors of integers and integer partitions seen as bi-infinite words. This methodology enables us on the one hand to obtain enumerations connect…

Macdonald Identities, Weyl-Kac Denominator Formulas and Affine Grassmannian Elements
Cédric Lecouvey, David Wahiche
The Nekrasov-Okounkov formula gives an expression for the Fourier coefficients of the Euler functions as a sum of hook length products. This formula can be deduced from a specializ…

Congruences for hook lengths of partitions
Frédéric Jouhet, David Wahiche
Recently, Amdeberhan et al. proved congruences for the number of hooks of fixed even length among the set of self-conjugate partitions of an integer , therefore answering positi…
