Continued fractions using a Laguerre digraph interpretation of the Foata-Zeilberger bijection and its variants [PDF]
In the combinatorial theory of continued fractions, the Foata-Zeilberger bijection and its variants have been extensively used to derive various continued fractions enumerating several (sometimes infinitely many) simultaneous statistics on permutations ...

Melham's conjecture on odd power sums of fibonacci numbers
Ozeki and Prodinger showed that the odd power sum of the first several consecutive Fibonacci numbers of even order is equal to a polynomial evaluated at a certain Fibonacci number of odd order. We prove that this polynomial and its derivative both vanish

Invariant cubature formulae for spheres and balls by combinatorial methods
. Invariant cubature formulae for a class of weight functions on the simplex T d are derived using combinatorial methods, extending the formulae in [Grundmann and Möller, SIAM J. Numer Anal., 15 (1978), pp.

Skeletal generalizations of chip-firing games, parking functions, and Dyck paths
For \(0\leq k\leq n-1\), we introduce a family of \(k\)-skeletal paths which are counted by the \(n\)th Catalan number for each \(k\), and specialize to Dyck paths when \(k=n-1\).

Generalizations of two identities of Guo and Yang
In this paper, we provide generalizations of two identities of Guo and Yang [2] for the q-binomial coefficients. This approach allows us to derive new convolution identities for the complete and elementary symmetric functions.

. A centrosymmetric permutation is one which is invariant under the reversecomplement operation, or equivalently one whose associated standard Young tableaux under the Robinson-Schensted algorithm are both invariant under the Schützenberger involution ...

Free fermionic probability theory and k-theoretic schubert calculus
For each of the four particle processes given by Dieker and Warren, we show the n-step transition kernels are given by the (dual) (weak) refined symmetric Grothendieck functions up to a simple overall factor. We do so by encoding the particle dynamics as

Bounded Littlewood identity related to alternating sign matrices
An identity that is reminiscent of the Littlewood identity plays a fundamental role in recent proofs of the facts that alternating sign triangles are equinumerous with totally symmetric self-complementary plane partitions and that alternating sign ...
