Eccentric distance sum index for some classes of connected graphs
Journal Title: Annales Universitatis Mariae Curie-Skłodowska. Sectio A, Mathematica - Year 2017, Vol 71, Issue 2
Abstract
In this paper we show some properties of the eccentric distance sum index which is defined as follows ξd(G)=∑v∈V(G)D(v)ε(v). This index is widely used by chemists and biologists in their researches. We present a lower bound of this index for a new class of graphs.

Convolution conditions for bounded α-starlike functions of complex order
Let A be the class of analytic functions in the unit disc U of the complex plane C with the normalization f(0)=f′(0)−1=0. We introduce a subclass S∗M(α,b) of A, which unifies the classes of bounded starlike and convex fu...
Invo-regular unital rings
It was asked by Nicholson (Comm. Algebra, 1999) whether or not unit-regular rings are themselves strongly clean. Although they are clean as proved by Camillo–Khurana (Comm. Algebra, 2001), recently Nielsen and ˇSter show...
The natural operators of general affine connections into general affine connections
We reduce the problem of describing all Mfm-natural operators transforming general affine connections on m-manifolds into general affine ones to the known description of all GL(Rm)-invariant maps Rm∗⊗Rm→⊗kRm∗⊗⊗kRm for k...
The density Turan problem for 3-uniform linear hypertrees. An efficient testing algorithm
Let T = (V, E) be a 3-uniform linear hypertree. We consider a blow-up hypergraph B[T ]. We are interested in the following problem. We have to decide whether there exists a blow-up hypergraph B[T ] of the hypertree T , w...
Some new inequalities of Hermite–Hadamard type for GA-convex functions
Some new inequalities of Hermite–Hadamard type for GA-convex functions defined on positive intervals are given. Refinements and weighted version of known inequalities are provided. Some applications for special means are...
