Walks confined in a quadrant are not always D-finite

Mireille Bousquet-Melou, Marko Petkovsek

We consider planar lattice walks that start from a prescribed position, take their steps in a given finite subset of Z^2, and always stay in the quadrant x >= 0, y >= 0. We first g…

Refined Restricted Permutations Avoiding Subsets of Patterns of Length Three

Toufik Mansour, Aaron Robertson

Define $S_{n}^{k} (T)$ to be the set of permutations of ${1, 2, ..., n}$ with exactly $k$ fixed points which avoid all patterns in $T \subseteq S_{m}$ . We enumerate $S_{n}^{k} (T)$ , $T \subsete…

Ideals of Quasi-Symmetric Functions and Super-Covariant Polynomials for S_n

J. -C. Aval, F. Bergeron, N. Bergeron

The aim of this work is to study the quotient ring R_n of the ring Q[x_1,...,x_n] over the ideal J_n generated by non-constant homogeneous quasi-symmetric functions. We prove here…
