Two common fixed Point theorems for compatible mappings
A.
Razani
M.
Yazdi
Recently, Zhang and Song [Q. Zhang, Y. Song, Fixed point theory for<br />generalized $varphi$-weak contractions,<br />Appl. Math. Lett. 22(2009) 75-78] proved a common fixed point theorem for two maps<br />satisfying generalized $varphi$-weak contractions. In this paper, we prove a common fixed point theorem for<br />a family of compatible maps. In fact, a new generalization of Zhang<br />and Song's theorem is given.

On the nature of solutions of the difference equation $mathbf{x_{n+1}=x_{n}x_{n-3}-1}$
C. M.

Kosmala
We investigate the long-term behavior of solutions of the difference equation<br /><br />[ x_{n+1}=x_{n}x_{n-3}-1 ,, n=0 ,, 1 ,, ldots ,, ]<br /><br />noindent where the initial conditions $x_{-3} ,, x_{-2} ,, x_{-1} ,, x_{0}$ are real numbers. In particular, we look at the periodicity and asymptotic periodicity of solutions, as well as the existence of unbounded solutions.

Equilibrium problems and fixed point problems for nonspreading-type mappings in hilbert space
U.
Singthong
S.
Suntai
In this paper by using the idea of mean convergence, we<br />introduce an iterative scheme for finding a common element of the<br />set of solutions of an equilibrium problem and the fixed points set<br />of a nonspreading-type mappings in Hilbert space. A strong<br />convergence theorem of the proposed iterative scheme is established<br />under some control conditions. The main result of this paper extend<br />the results obtained by Osilike and Isiogugu (Nonlinear Analysis 74<br />(2011) 1814-1822) and Kurokawa and Takahashi (Nonlinear Analysis 73<br />(2010) 1562-1568). We also give an example and numerical results are<br />also given.

On absolute generalized Norlund summability of double orthogonal series
X. Z.
Krasniqi
In the paper [Y. Okuyama, {it On the absolute generalized N"{o}rlund summability of orthogonal series},<br />Tamkang J. Math. Vol. 33, No. 2, (2002), 161-165] the author has found some sufficient conditions under which an orthogonal series<br />is summable $|N,p,q|$ almost everywhere. These conditions are expressed in terms of coefficients of the series. It is the purpose of<br />this paper to extend this result to double absolute summability $|N^{(2)},mathfrak{p},mathfrak{q}|_k$, $(1leq kleq 2)$

A new class of nonlinear set-valued variational<br />inclusions involving $(A,eta)$-monotone mappings in a Banach<br />space setting is introduced, and then based on the generalized<br />resolvent operator technique associated with<br />$(A,eta)$-monotonicity, the existence and approximation<br />solvability of solutions using an iterative algorithm and fixed<br />pint theory is investigated.

For an arbitrary entire function f(z), let M(f;R) = maxjzj=R jf(z)j<br />and m(f; r) = minjzj=r jf(z)j.
