The proposed method combines a time scheme based on the predictor-corrector method and the Crank-Nicolson scheme for the spatial discretization.

BounkhelDepartment of Mathematics, College of Science, King Saud University, Saudi ArabiaIn this paper, we investigate the existence of common fixed points of monotone Lipschitzian semigroup in Banach spaces under the natural condition that the images under the action of the semigroup at certain point are comparable to the point. In particular, we prove that if one map in the semigroup is a monotone contraction mapping, then such common fixed point exists. In the case of monotone nonexpansive semigroup we prove the existence of common fixed points if the Banach space is uniformly convex in every direction. This assumption is weaker than uniform convexity.http://isr-publications.com/jnsa/6518/download-common-fixed-points-of-monotone-lipschitzian-semigroups-in-banach-spacesInternational Scientific Research PublicationsJournal of Nonlinear Sciences and Applications(JNSA)ISSN 2008-190111120171224On the rational difference equation \(y_{{n+1}}={\frac {\alpha_{{0}}y_{{n}}+\alpha_{{1}}y_{{n-p}}+\alpha_{{2}}y_{{n-q}} +\alpha_{{3}}y_{{n-r}}+\alpha_{{4}}y_{{n-s}}}{\beta_{{0}}y_{{n}}+\beta_{{1}}y_{{n-p} }+\beta_{{2}}y_{{n-q}}+\beta_{{3}}y_{{n-r}}+\beta_{{4}}y_{{n-s}}}}\)8097http://dx.doi.org/10.22436/jnsa.011.01.07ENA.

In order to clarify the mathematical structure of
contractions of rational type,
we generalize this theorem in a general setting.http://isr-publications.com/jnsa/6534/download-fixed-point-theorems-for-contractions-of-rational-type-in-complete-metric-spacesInternational Scientific Research PublicationsJournal of Nonlinear Sciences and Applications(JNSA)ISSN 2008-190111120171231Accelerated hybrid iterative algorithm for common fixed points of a finite families of countable Bregman quasi-Lipschitz mappings and solutions of generalized equilibrium problem with application108130http://dx.doi.org/10.22436/jnsa.011.01.09ENJingling ZhangDepartment of Mathematics, Tianjin University, Tianjin 300350, P. R. ChinaRavi P. AgarwalDepartment of Mathematics, Texas A \(\&\) M University-Kingsville, Texas 78363, USA.Nan JiangDepartment of Mathematics, Tianjin University, Tianjin 300350, P. R. ChinaThe purpose of this paper is to introduce and consider a new
accelerated hybrid shrinking projection method for finding a
common element of the set \(EP \cap F\) in reflexive Banach spaces,
where \(EP\) is the set of all solutions of a generalized equilibrium problem,
and \(F\) is the common fixed point set of finite uniformly closed families of
countable Bregman quasi-Lipschitz mappings.
It is proved that the sequence generated by the accelerated
hybrid shrinking projection iteration, converges strongly to the
point in \(EP \cap F,\) under some conditions. This result is also
applied to find the fixed point of Bregman asymptotically
quasi-nonexpansive mappings.
It is worth mentioning that, there are multiple projection
points from the multiple points in the projection algorithm.
Therefore the new projection method in this paper can accelerate the convergence
speed of iterative sequence. The new results improve and extend
the previously known ones in the literature.
