The double star sequences and the general second Zagreb index
Journal Title: Математичні Студії - Year 2019, Vol 51, Issue 2
Abstract
For a simple graph we introduce notions of the double star sequence, the double star fre- quently sequence and prove that these sequences are inverses of each other. As a consequence, we express the general second Zagreb index in terms of the double star sequence. Also, we calculate the ordinary generating function and a linear recurrence relation for the sequence of the general second Zagreb indexes.

On removable singularities of mappings in uniform spaces
The paper is devoted to the study of mappings of two metric spaces that distort the modulus of families of paths by analogy with the Poletskii inequality.We deal with the situation when the mapping acts in a space that a...
An extremal problem for volume functionals
We consider the class of ring Q-homeomorphisms with respect to p-modulus in Rn with p>n, and obtain a lower bound for the volume of images of a ball under such mappings. In particular, the following theorem is proved in...
Locally univalence of Dirichlet series satisfying a linear differential equation of second order with exponential coefficients
Let h>0, γ0≠0, γ1≠0, γ2≤−1 and |γ1|/4+|γ0|/6≤h/5. It is well-proven that the differential equation w′′+(γ0e2hs+γ1ehs+γ2)w=0 has an entire solution F(s)=exp{sλ1}+∑∞k=2fkexp{sλk} locally univalent in the half-plane {s:Res≤...
Dual pair of eigenvalues in rank one singular nonsymmetric perturbations
In the separable Hilbert space, we discuss the eigenvalue problem for a rank one singular nonselfadjoint perturbation of a selfadjoint operator A, by nonsymmetric potential (δ1≠δ2) in the form A~=A+α⟨⋅,δ1⟩δ2. We give the...
Asymptotic behaviour of means of nonpositive M-subharmonic functions
We describe growth and decrease of pth means, 1≤p≤2n−12(n−1), of nonpositive M-subharmonic functions in the unit ball in Cn in terms of smoothness properties of a measure. As consequence we obtain a haracterization of as...
