Some relations between Kekule structure and Morgan-Voyce polynomials
Authors
Abstract:
In this paper, Kekule structures of benzenoid chains are considered. It has been shown that the coefficients of a B_n (x) Morgan-Voyce polynomial equal to the number of k-matchings (m(G,k)) of a path graph which has N=2n+1 points. Furtermore, two relations are obtained between regularly zig-zag nonbranched catacondensed benzenid chains and Morgan-Voyce polynomials and between regularly zig-zag nonbranched catacondensed benzenid chains and their corresponding caterpillar trees.

Generalizations of Modified Morgan-voyce Polynomials
In two recent articles [2] and [3], Ferri et al. introduced and studied the properties of two numerical triangles, which they called DFF and DFZ triangles. However, in a subsequent article, Andre-Jeannin [1] showed that the polynomials generated by the rows of these triangles are indeed the Morgan-Voyce polynomials Bn{x) and bn(x), whose properties are well known [10] and [11]; in fact, the pol...

111 recent years, a number of papers appeared on the subject of generalization of the MorganVoyce (Mr) polynomials (see5 e.g., Andre-Jeannin [l]-[3] and Horadam [4]-[7]). The richness of results in these works prompted our Investigation on this subject. We further generalized the Mpolynomials in a particular way and obtained some new relations by means of the line-sequential formalism developed...
full textSome psychological relations between action and language structure.
This study investigated the relationship between complex grammatical structures and complex action sequences. A developmental progression of strategies for combining seriated cups identified in an earlier study (Greenfield et al., 1972) was used to demonstrate some psychological consequences of formal parallels between language and action. The role of grammatical complexity and situational stru...

Abstract. This paper deals with the study of the generalized hypergeometric matrix function and obtains some of its properties. We rephrase some results from the previous (earlier) works that will be used in this study. We get the hypergeometric matrix function representation, matrix differential equation, generating matrix functions, bilinear generating matrix functions, matrix recurrence rela...
full textSome Relations on Laguerre Matrix Polynomials
The main object of this paper is to give a di erent approach to proof of generating matrix functions for Laguerre matrix polynomials. We also obtain the hypergeometric matrix representations, addition theorem, nite summation formula and an integral representation for Laguerre matrix polynomials. We get the relations between Laguerre, Legendre and Hermite matrix polynomials. We get the generatin...

It is known that, in general, the coboundary polynomial and the Möbius polynomial of a matroid do not determine each other. Less is known about more specific cases. In this paper, we will investigate if it is possible that the Möbius polynomial of a matroid, together with the Möbius polynomial of the dual matroid, define the coboundary polynomial of the matroid. In some cases, the answer is aff...
