Song, Fixed point theory for generalized $varphi$-weak contractions, Appl. Math. Lett. 22(2009) 75-78] proved a common fixed point theorem for two maps satisfying generalized $varphi$-weak contractions. In this paper, we prove a common fixed point theorem for a family of compatible maps. In fact, a new generalization of Zhang and Song's theorem is given.Semnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-68222220110601New inequalities for a class of differentiable functions19238910.22075/ijnaa.2011.89ENZ.DahmaniLaboratory of Pure and Applied Mathematics, Faculty of SESNV, UMAB, University of Mostaganem Adelhamid Ben Badis, AlgeriaJournal Article20111220In this paper, we use the Riemann-Liouville fractional integrals to establish some new integral inequalities related to Chebyshev's functional in the case of two differentiable functions.Semnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-68222220110601On the nature of solutions of the difference equation $mathbf{x_{n+1}=x_{n}x_{n-3}-1}$24439110.22075/ijnaa.2011.91ENC.

Chiang Mai University, Chiang Mai 50200, ThailandJournal Article20101221In this paper by using the idea of mean convergence, we introduce an iterative scheme for finding a common element of the set of solutions of an equilibrium problem and the fixed points set of a nonspreading-type mappings in Hilbert space. A strong convergence theorem of the proposed iterative scheme is established under some control conditions. The main result of this paper extend the results obtained by Osilike and Isiogugu (Nonlinear Analysis 74 (2011) 1814-1822) and Kurokawa and Takahashi (Nonlinear Analysis 73 (2010) 1562-1568). We also give an example and numerical results are<br />also given.Semnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-68222220110601On absolute generalized Norlund summability of double orthogonal series62749610.22075/ijnaa.2010.96ENX.

Vol. 33, No. 2, (2002), 161-165] the author has found some sufficient conditions under which an orthogonal series is summable $|N,p,q|$ almost everywhere. These conditions are expressed in terms of coefficients of the series. It is the purpose of this paper to extend this result to double absolute summability $|N^{(2)},mathfrak{p},mathfrak{q}|_k$, $(1leq kleq 2)$.Semnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-68222220110601A Class of nonlinear $(A,eta)$-monotone operator inclusion problems with iterative algorithm and fixed point theory75859910.22075/ijnaa.2011.99ENM.AlimohammadyDepartment of Mathematics, University of

If $P(z)$ is a polynomial of degree $n$ having no zeros in $|z| < k, k geq 1$, then for $0 leq r leqrholeq k$, it is proved by Aziz et al. that<br />$$M(P',rho)leqfrac{n}{rho+k}{(frac{rho+k}{r+k})^n[1-frac{(k-rho)(n|a_0|-k|a_1|)n}{(rho^2+k^2)n|a_0|+2k^2rho |a_1|}(frac{rho-r}{k+r})(frac{k+1}{k+rho})^{n-1}]M(P,r)$$<br />$$-[frac{(n|a_0|rho+k^2|a_1|)(r+k)}{(rho^2+k^2)n|a_0|+2k^2rho|a_1|}times[((frac{rho+k}{r+k})^n-1)-n(rho-r)]]m(P,k)}$$<br />In this paper, we obtain a refinement of the above inequality.
