Mathematical results on the H-index and H-sequence of Randić

چکیده

We present mathematical formulae for the H-sequence and H-index of Randić in a Lotkaian framework. We also present a variant of the H-index of Randić. We prove that the following assertions are equivalent, given two persons with the same hindex of Hirsch: the Randić H-index 1 H of the first person is larger than 2 H , the one of the second person, if and only if the H-sequence of the first person dominates the one of the second person. These properties are equivalent with 1 2    (where   1,2 i i   are the Lotka exponents of the two persons) and also equivalent with 1 2    (where   1,2 i i   is the average number of citations per article of the two persons). 1 Permanent address

Subspace-diskcyclic sequences of linear operators

A sequence ${T_n}_{n=1}^{infty}$ of bounded linear  operators on a separable infinite dimensional Hilbert space $mathcal{H}$ is called subspace-diskcyclic with respect to the closed subspace $Msubseteq mathcal{H},$ if there exists a vector $xin mathcal{H}$ such that the disk-scaled orbit ${alpha T_n x: nin mathbb{N}, alpha inmathbb{C}, | alpha | leq 1}cap M$ is dense in $M$. The goal of t...

Some New Results On the Hosoya Polynomial of Graph Operations

The Wiener index is a graph invariant that has found extensive application in chemistry. In addition to that a generating function, which was called the Wiener polynomial, who’s derivate is a q-analog of the Wiener index was defined. In an article, Sagan, Yeh and Zhang in [The Wiener Polynomial of a graph, Int. J. Quantun Chem., 60 (1996), 959969] attained what graph operations do to the Wiene...

On the distance based indices of H-phenylenic nanotorus

Let G be a connected simple (molecular) graph. The distance d(u, v) between two vertices u and v of G is equal to the length of a shortest path that connects u and v. In this paper we compute some distance based topological indices of H-Phenylenic nanotorus. At first we obtain an exact formula for the Wiener index. As application we calculate the Schultz index and modified Schultz index of this...

MULTI-OBJECTIVE MATHEMATICAL MODELING OF AIRCRAFT LANDING PROBLEM ON A RUNWAY IN STATIC MODE, SCHEDULING AND SEQUENCE DETERMINATION USING NSGA-II

Runway length is usually a critical point in an airport system so, a great interest has been created for optimal use of this runway length. The most important factors in modeling of aircraft landing problem are time and cost while, the costs imposed on the system because of moving away from target times have different performances in terms of impact. In this paper, firstly, aircraft landing pro...

On difference sequence spaces defined by Orlicz functions without convexity

In this paper, we first define spaces of single difference sequences defined by a sequence of Orlicz functions without convexity and investigate their properties. Then we extend this idea to spaces of double sequences and present a new matrix theoretic approach construction of such double sequence spaces.
