Semifinite Harmonic Functions on the Zigzag Graph
نویسندگان
چکیده
We study semifinite harmonic functions on the zigzag graph, which corresponds to Pieri rule for fundamental quasisymmetric $$\{F_{\lambda}\}$$ . The main problem, we solve here, is classify indecomposable this graph. show that these are in a natural bijective correspondence with some combinatorial data, so-called growth models. Furthermore, describe an explicit construction produces function from every model. also establish analogue of Vershik–Kerov ring theorem.

on the harmonic index of graph operations
the harmonic index of a connected graph $g$, denoted by $h(g)$, is defined as $h(g)=sum_{uvin e(g)}frac{2}{d_u+d_v}$ where $d_v$ is the degree of a vertex $v$ in g. in this paper, expressions for the harary indices of the join, corona product, cartesian product, composition and symmetric difference of graphs are derived.
متن کاملSome Results on Nonlinear Zigzag Functions
Zigzag functions were deened by Brassard, Cr epeau and SS antha 1] in connection with an application to the construction of oblivious transfers (a useful tool in cryptographic protocols). They proved that linear zigzag functions are equivalent to self-intersecting codes, which have been studied by several researchers. In this paper, we begin an investigation of general (linear or non-linear) zi...
متن کاملSemifinite Spectral Triples Associated with Graph C-algebras
We review the recent construction of semifinite spectral triples for graph C∗algebras. These examples have inspired many other developments and we review some of these such as the relation between the semifinite index and the Kasparov product, examples of noncommutative manifolds, and an index theorem in twisted cyclic theory using a KMS state.

متن کاملOn Univalent Harmonic Functions
Two classes of univalent harmonic functions on unit disc satisfying the conditions ∑∞ n=2(n−α)(|an|+|bn|) ≤ (1−α)(1−|b1|) and ∑∞ n=2 n(n−α)(|an|+|bn|) ≤ (1−α)(1−|b1|) are given. That the ranges of the functions belonging to these two classes are starlike and convex, respectively. Sharp coefficient relations and distortion theorems are given for these functions. Furthermore results concerning th...
