Complete determination of the zeta function of the Hilbert scheme of points on a two-dimensional torus
Christian Kassel, Christophe Reutenauer
We compute the coefficients of the polynomials defined by the equation \begin{equation*} 1 + \sum_{n\geq 1} \, \frac{C_n(q)}{q^n} \, t^n = \prod_{i\geq 1}\, \frac{(1-t^i)^…
The Fourier expansion of η(z)η(2z)η(3z)/η(6z)
Christian Kassel, Christophe Reutenauer
We compute the Fourier coefficients of the weight one modular form in terms of the number of representations of an integer as a sum of two squares. We deduce…
Linearly recursive sequences and Dynkin diagrams
Christophe Reutenauer
Motivated by a construction in the theory of cluster algebras (Fomin and Zelevinsky), one associates to each acyclic directed graph a family of sequences of natural integers, one f…
Christoffel words and Markoff triples
Christophe Reutenauer
Markoff triples are parametrized uniquely by Christoffel words.
