On the small-step quarter plane lattice walks with a non D-finite univariate generating function

Marni Mishna, Juan Pulido

We report on the status of the conjecture of Bousquet-Mélou and Mishna that the univariate counting generating function of a small-step quarter-plane lattice model is D-finite if a…

Differential transcendence and walks on self-similar graphs

Yakob Kahane, Marni Mishna

Symmetrically self-similar graphs are an important type of fractal graph. Their Green functions satisfy order one iterative functional equations. We show when the branching number…

Uniform Sampling and Visualization of 3D Reluctant Walks

Benjamin Buckley, Marni Mishna

A family of walks confined to the first orthant whose defining stepset has drift outside of the region can be challenging to sample uniformly at random for large lengths. We addres…

Differential equations satisfied by generating functions of 5-, 6-, and 7-regular labelled graphs: a reduction-based approach

Frédéric Chyzak, Marni Mishna

By a classic result of Gessel, the exponential generating functions for -regular graphs are D-finite. Using Gröbner bases in Weyl algebras, we compute the linear differential eq…

Inhomogeneous order 1 iterative functional equations with applications to combinatorics

Lucia Di Vizio, Gwladys Fernandes, Marni Mishna

We show that if a Laurent series satisfies a particular kind of linear iterative equation, then is either a rational function or it is differentially tran…

Estimating and computing Kronecker Coefficients: a vector partition function approach

Marni Mishna, Stefan Trandafir

We study the Kronecker coefficients via a formula that was described by Mishna, Rosas, and Sundaram, in which the coefficients are expressed as a signed sum of vector…
