The (2,1) -Total Labeling of Sn+1∨Pm and Sn+1×Pm  [PDF]
Sumei Zhang, Qiaoling Ma, Jihui Wang
Applied Mathematics (AM) , 2010, DOI: 10.4236/am.2010.15048
Abstract: The (2,1)-total labeling number of a graph is the width of the smallest range of integers that suffices to label the vertices and the edges of such that no two adjacent vertices have the same label, no two adjacent edges have the same label and the difference between the labels of a vertex and its incident edges is at least 2. In this paper, we studied the upper bound of of Sn+1∨Pm and Sn+1×Pm
Bondage Number of 1-Planar Graph  [PDF]
Qiaoling Ma, Sumei Zhang, Jihui Wang
Applied Mathematics (AM) , 2010, DOI: 10.4236/am.2010.12013
Abstract: The bondage number of a nonempty graph G is the cardinality of a smallest set of edges whose removal from G results in a graph a domination number greater than the domination number of G. In this paper, we prove that for a 1-planar graph G.
Existence of multiple positive solutions for third-order boundary-value problem on the half-line with dependence on the first order derivative
Sihua Liang,Jihui Zhang
Electronic Journal of Differential Equations , 2009,
Abstract: By using fixed-point theorem for operators on a cone, sufficient conditions for the existence of multiple positive solutions for a third-order boundary-value problem on the half-line are established. In the case of the p-Laplace operator our results for p>1 generalize previous known results. The interesting point lies in the fact that the nonlinear term is allowed to depend on the first order derivative u'.
Periodic solutions of non-autonomous second order systems with p-Laplacian
Zhiyong Wang,Jihui Zhang
Electronic Journal of Differential Equations , 2009,
Abstract: We prove the existence of periodic solutions for non-autonomous second order systems with p-Laplacian. Our main tools are the minimax methods in critical point theory. Our results are new, even when p=2.
Multiplicity of positive solutions for a Navier boundary-value problem involving the p-biharmonic with critical exponent
Ying Shen,Jihui Zhang
Electronic Journal of Differential Equations , 2011,
Abstract: By using the Nehari manifold and variational methods, we prove that a p-biharmonic system has at least two positive solutions when the pair the parameters satisfy certain inequality.
Existence of positive solutions for quasilinear elliptic systems involving the p-Laplacian
Xudong Shang,Jihui Zhang
Electronic Journal of Differential Equations , 2009,
Abstract: In this article, we study the existence of positive solutions for the quasilinear elliptic system $$displaylines{ -Delta_{p}u = f(x,u,v) quad x in Omega ,cr -Delta_{p}v = g(x,u,v) quad x in Omega ,cr u = v = 0 quad x in partialOmega. }$$ Using degree theoretic arguments based on the degree map for operators of type $(S)_{+}$, under suitable assumptions on the nonlinearities, we prove the existence of positive weak solutions.
Existence and Iteration of Positive Solutions for One-Dimensional p-Laplacian Boundary Value Problems with Dependence on the First-Order Derivative
Zhiyong Wang,Jihui Zhang
Boundary Value Problems , 2008, DOI: 10.1155/2008/860414
Abstract: This paper deals with the existence and iteration of positive solutions for the following one-dimensional p-Laplacian boundary value problems: ( p(u ¢ € 2(t))) ¢ € 2+a(t)f(t,u(t),u ¢ € 2(t))=0, t ¢ (0,1), subject to some boundary conditions. By making use of monotone iterative technique, not only we obtain the existence of positive solutions for the problems, but also we establish iterative schemes for approximating the solutions.

Wang Zhiyong,Zhang Jihui
Boundary Value Problems , 2011,
Abstract: Some existence and multiplicity of periodic solutions are obtained for nonautonomous second order Hamiltonian systems with sublinear nonlinearity by using the least action principle and minimax methods in critical point theory. Mathematics Subject Classification (2000): 34C25, 37J45, 58E50.

Existence results for a class of nonlocal problems involving p-Laplacian
Yang Yang,Zhang Jihui
Boundary Value Problems , 2011,
Abstract: This paper is concerned with the existence of solutions to a class of p-Kirchhoff type equations with Neumann boundary data as follows: - M ∫ Ω u p d x p - 1 Δ p u = f ( x , u ) , in Ω ; u υ = 0 , on Ω . By means of a direct variational approach, we establish conditions ensuring the existence and multiplicity of solutions for the problem.
