The the electronic journal of combinatorics 17 (2010), #R3 3 to be non-holonomic as soon as the set of of poles of φ(s) ... (φ(n)) n1 is not holonomic. Proof. This follows readily from the expansion (18) and the holonomicity criterion (1). Without loss of generality, we assume that s 1 has maximal real part among...

One possibility is to consider the following generalization of the complete ... has no node whose only child is a left child. Proof. We have s n−1 > s n if and only if the rightmost node s n has a (lone) left child. The proposition now follows from Lemma 7....

Boros and Moll then point out that showing that the binomial coeffi- cients are ∞-logconcave (project 7.9.3 in [1]) would go a long ... belong to one of the above cases. Our approach to the problem is the following: for a given sequence of the form above of length 2n + 3 or 2n + 4 we analyze the dynamics of L on the subset o...

... around each vertex is π. A f-tiling τ is said to be monohedral if it is composed by congruent cells, and dihedral if every tile of τ is congruent to one of two fixed sets X and Y (prototiles of ... Introduction Spherical folding tilings or f-tilings for short, are edge-to-edge decompositions of the sphere by geodesic polygons, such that all vertices are of even valency and the sum of alt...
