<abstract><p>Let $ A(G) and D(G) be the adjacency matrix degree diagonal of a graph G $, respectively. For any real number \alpha \in[0, 1] Nikiforov defined A_{\alpha} $-matrix as A_{\alpha}(G) = D(G)+(1-\alpha)A(G) $. Let S_k(A_{\alpha}(G)) sum k largest eigenvalues In this paper, some bounds on are obtained, which not only extends results signless Laplacian matrix, but it also gi...
In this article, the Varshni potential is analyzed taking into consideration effects of magnetic and AB flux fields within non-relativistic regime using Nikiforov-Uvarov-Functional Analysis method (NUFA) method. The energy equation wave function system are obtained in close form. We find that entirety these removes degeneracy as a consequence raises bound state system. More so, it could be dedu...
In this study, we apply the parametric Nikiforov-Uvarov method to obtain bound state solution of Schrödinger wave equation in presence Kratzer plus generalized Morse potential (KPGM). The energy eigen and corresponding normalised function were obtained closed form. resulting was used study partition other thermodynamic properties such as vibrational mean energy, specific heat capacity, free ent...

Li, Nikiforov and Schelp [12] conjectured that any 2-edge coloured graph G with order n and minimum degree δ(G) > 3n/4 contains a monochromatic cycle of length `, for all ` ∈ [4, dn/2e]. We prove this conjecture for sufficiently large n and also find all 2-edge coloured graphs with δ(G) = 3n/4 that do not contain all such cycles. Finally, we show that, for all δ > 0 and n > n0(δ), if G is a 2-e...
Approximate l-state solutions of the D-dimensional Schrödinger equation for Manning-Rosen potential
The Schrödinger equation in D-dimensions for the Manning-Rosen potential with the centrifugal term is solved approximately to obtain bound states eigensolutions (eigenvalues and eigenfunctions). The Nikiforov-Uvarov (NU) method is used in the calculations. We present numerical calculations of energy eigenvalues to twoand four-dimensional systems for arbitrary quantum numbers n and l with three ...
The goal of this paper is to show that recent advances in change-point detection theory, as described in Basseville and Nikiforov (1993), Dragalin (1995,1996), Lai (1995,1998), Pollak (1985,1987), Tartakovsky (2003), and others, can be successfully applied to (i) certain practical problems related to rapid detection of targets in multichannel and multisensor distributed systems, and (ii) the pr...

The title complex, [Hf(C29H41N2)Cl3], was synthesized from HfCl4 and HC[C(Me)N( (i) Pr2C6H3)]2Li(Et2O) in toluene. The structure is isotypic with those of Ti(IV) and Zr(IV) complexes reported previously [Nikiforov et al. (2007 ▶). Dalton Trans. pp. 4149-4159; Kakaliou et al. (1999 ▶). Inorg. Chem. 38, 5964-5977]. There is a crystallographic mirror plane containing the Hf atom, one chloride liga...
