Hankel determinants of some polynomial sequences
Johann Cigler
We give simple new proofs of some Hankel determinant evaluations by Omer Egecioglu and Aleksandar Cvetkovic, Predrag Rajkovic and Milos Ivkovic and prove analogous results for sums…
A natural stochastic extension of the sandpile model on a graph
Yao-ban Chan, Jean-François Marckert, Thomas Selig
We introduce a new model of a stochastic sandpile on a graph containing a sink. When unstable, a site sends one grain to each of its neighbours independently with probability $…
A note on 5-cycle double covers
Arthur Hoffmann-Ostenhof
The strong cycle double cover conjecture states that for every circuit of a bridgeless cubic graph , there is a cycle double cover of which contains . We conjecture t…
q-Chebyshev polynomials
Johann Cigler
In this overview paper a direct approach to q-Chebyshev polynomials and their elementary properties is given. Special emphasis is placed on analogies with the classical case. There…
