Exact bounds for some basis functions of approximation operators

open access: yesJournal of Inequalities and Applications, 2001
The exact bounds of Bernstein basic functions and Meyer-Konig and Zeller basis functions have been determined in [J. Math. Anal. Appl., 219 (1998), 364–376].

DECOMPOSITION METHOD FOR SOLVING FULLY FUZZY LINEAR SYSTEMS [PDF]

open access: yesIranian Journal of Optimization, 2010
In this paper, we investigate the existence of a positive solution of fully fuzzy linear equation systems. This paper mainly to discuss a new decomposition of a nonsingular fuzzy matrix, the symmetric times triangular (ST) decomposition.

A characterisation of infinity-harmonic and p-harmonic maps via affine variations in L-infinity

open access: yesElectronic Journal of Differential Equations, 2017
Let $u: \Omega \subseteq \mathbb{R}^n \to \mathbb{R}^N$ be a smooth map and $n,N \in \mathbb{N}$. The $\infty$-Laplacian is the PDE system $$ \Delta_\infty u :=\Big(Du \otimes Du + |Du|^2[Du]^\bot \otimes I\Big) :D^2u = 0, $$ where $[Du]^\bot ...

Note on the skew energy of oriented graphs [PDF]

open access: yesTransactions on Combinatorics, 2015
The skew energy of oriented graphs is de ned as the sum of the norms of all the eigenvalues of the skew adjacency matrix. In this note, we obtain some upper bounds for the skew energy of any oriented graphs, which improve the known upper bound ...

Bifurcation for non linear ordinary differential equations with singular perturbation

open access: yesElectronic Journal of Differential Equations, 2016
We study a family of singularly perturbed ODEs with one parameter and compare their solutions to the ones of the corresponding reduced equations. The interesting characteristic here is that the reduced equations have more than one solution for a ...

The hyper edge-Wiener index of corona product of graphs [PDF]

open access: yesTransactions on Combinatorics, 2015
Let G be a simple connected graph. The edge-Wiener index W e (G) is the sum of all distances between edges in G , whereas the hyper edge-Wiener index WW e (G) is defined as {\footnotesize WW e (G)=12 W e (G)+12 W 2 e (G) }, where {footnotesize W 2 e ...

Long Noncoding RNA HEIH Promotes Colorectal Cancer Tumorigenesis via Counteracting miR-939‒Mediated Transcriptional Repression of Bcl-xL

open access: yesCancer research and treatment : official journal of Korean Cancer Association, 2017
Purpose Studies have found that long noncoding RNA HEIH (lncRNA-HEIH) is upregulated and facilitates hepatocellular carcinoma tumor growth. However, its clinical significances, roles, and action mechanism in colorectal cancer (CRC) remains unidentified ...

Singular integrals of the time-harmonic relativistic Dirac equation on a piecewise Liapunov surface

open access: yesElectronic Journal of Differential Equations, 2005
We give a short proof of a formula of Poincare-Bertrand in the setting of time-harmonic solutions of the relativistic Dirac equation on a piecewise Liapunov surface, as well as for some versions of quaternionic analysis.

On existence of optimal controls in coecients for ill-posed nonlinear elliptic Dirichlet boundary value problems with anisotropic p-Laplacian

open access: yesVìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Modelûvannâ, 2016
We study a Dirichlet optimal control problem for a nonlinear elliptic anisotropic p-Laplace equation with control and state constraints. The matrix-valued coecients we take as controls and in the linear part of dierential operator we consider coecients ...
