Abstract:
Some new oscillation criteria for second-order linear delay dynamic equation
on a time scale T are established. Our results improve the
recent results for delay dynamic equations and in the special case when
T=R, the results include the oscillation results established by Hille [1948,
Trans. Amer. Math. Soc. 64 (1948), 234-252] and Erbe [Canad. Math. Bull. 16
(1973), 49-56.] for differential equations. When T=Z the
results include and improve some oscillation criteria for difference
equations. When T=hZ, h>0, T=qN and T=N2, i.e., for generalized second order delay difference equations our
results are essentially new and can be applied on different types of time
scales. An example is considered to illustrate the main results.

Abstract:
Some oscillation and boundedness criteria for solutions to certain
first and second order forced dynamic equations
with mixed nonlinearities are established. The main tool in the proofs
is an inequality due to Hardy, Littlewood and Pólya.
The obtained results can be applied to differential equations,
difference equations and q-difference equations. The results
are illustrated with numerous examples.

Abstract:
This paper investigates discrete boundary value problems (BVPs) involving second-order difference equations and two-point boundary conditions.
General theorems guaranteeing the existence and uniqueness of solutions to the discrete BVP are established. The methods involve a sufficient growth condition to yield an a priori bound on solutions to a certain family of discrete BVPs. The em a priori bounds on solutions to the discrete BVP do not depend on the step-size and thus there are no ``spurious'' solutions. It is shown that solutions of the discrete BVP will converge to solutions of ordinary differential equations.

Abstract:
This paper is concerned with second-order linear noncanonical delay difference equations of the form
Δ(μ(t)Δ y(t))+ p(t)y(φ(t))=0.
The authors prove new oscillation criteria by first transforming the equation into canonical form and then obtaining some new monotonic properties of the positive solutions of the transformed equation. By using a comparison with first-order delay difference equations and a generalization of a technique developed by Koplatadze, they obtain their main results. Examples illustrating the improvement over known results in the literature are presented.

Abstract:
In this paper, we investigate the complete monotonicity of some functions involving gamma function. Using the monotonic properties of these functions, we derived some inequalities involving gamma and beta functions. Such inequalities can be used to generalize different probability distribution functions. Also, they can be used to generalize some statistical designs, e.g., the probability proportional to the size without replacement design.

Positive Solutions of Evolution Operator Equations
Author(s):
Radu Precup
Department of Applied Mathematics,
Babes-Bolyai University,
Cluj, Romania
Abstract:
Existence and localization results are derived from Krasnoselskii’s compressionexpansion
fixed point theorem in cones, for operator equations in spaces of continuous functions
from a compact real interval to an abstract space. The main idea, first used in [12], is to handle
two equivalent operator forms of the equation, one of fixed point type giving the operator to
which Krasnoselskii’s theorem applies and an other one of coincidence type which is used to
localize a positive solution in a shell. An application is presented for a boundary value problem
associated to a fourth order partial differential equation on a rectangular domain.

Abstract:
In this paper we establish some new nonlinear integro-differential inequalities of Gronwall-Bellman-Pachpatte type for function of one independent variable. The purpose of this paper is to extend certain results which proved by Pachpatte in [On some fundamental integrodifferential and integral inequalities, An. Sti. Univ. Al. I. Cuza, Iasi, Vol.23 (1977), 77-86]. The inequalities obtained here can be used in the theory of some new classes of nonlinear integro-differential equations. Some applications are also given to illustrate the usefulness of our results. Paper's Title:
Strong Convergence Theorem for a Common Fixed Point of an
Infinite Family of J-nonexpansive Maps with Applications Author(s):
Charlse Ejike Chidume, Otubo Emmanuel Ezzaka and Chinedu Godwin Ezea African University of Science and
Technology, Ebonyi State University, Nnamdi Azikiwe University, Abstract:
Let E be a uniformly convex and uniformly smooth real Banach space with dual space
E*. Let {Ti}∞i=1 be a family of
J-nonexpansive maps, where, for each i,~Ti maps E to 2E*.
A new class of maps, J-nonexpansive maps from E to E*, an
analogue of nonexpansive self maps of
E, is introduced. Assuming that the set of common J-fixed points
of {Ti}∞i=1 is nonempty, an iterative scheme is constructed and proved
to converge strongly to a point x* in ∩∞n=1FJTi. This result is then applied, in the case that
E is a real Hilbert space to obtain
a strong convergence theorem for approximation of a common fixed point for an infinite family of nonexpansive maps, assuming existences. The theorem
obtained is compared with some important results in the literature. Finally, the technique of proof is also of independent interest. Paper's Title:

Naresh Kumar and Renu Chugh Department of Mathematics, Abstract:
The aim of this paper is to introduce a new iteration process
(5) for ρ-contraction mappings in Modular spaces. We obtain some analytical proof for convergence and stability of our iteration process
(5). We show that our iteration process (5) gives faster convergence results than the leading AK iteration process
(4) for contraction mappings.
Moreover, a numerical example (using the Matlab Software) is presented to compare the rate of convergence for existing iteration processes with our new iteration process
(5). Paper's Title:

A new iterative algorithm is constructed and proved to converge strongly to a
common zero of the family.
As a consequence of this result, a strong convergence theorem for approximating
a common J-fixed point for an infinite family of
gamma-strictly J-pseudocontractive maps is proved. These results are new and
improve recent results obtained for these classes of nonlinear maps.
Furthermore, the technique of proof is of independent interest.

Abstract:
Non homogeneous fractional diffusion-wave equation has been solved under linear/nonlinear boundary conditions. As the order of time derivative changes from
0 to 2, the process changes from slow diffusion to classical diffusion to mixed diffusion-wave behaviour.
Numerical examples presented here confirm this inference. Orthogonality of eigenfunctions in case of fractional Stürm-Liouville problem has been established

coerciveness of the solution of the considered problem, the completeness of
system of root vectors in Banach-valued functions spaces and we establish
the Abel basis property of this system in Hilbert spaces. Finally, we apply
this abstract results to a partial differential equation in cylindrical

The common fixed point results for Banach operator pair with generalized nonexpansive mappings in q-normed space have been obtained in the present work. As application, some more general best approximation results have also been determined without the assumption of linearity or affinity of mappings. These results unify and generalize various existing known results with the aid of more general class of noncommuting mappings.

Abstract:
In this paper, we propose and analyze a type of subgradient extragradient algorithm for the approximation of a solution of variational inequality problem which is also a common fixed point of an infinite family of relatively nonexpansive mappings in 2-uniformly convex Banach spaces which are uniformly smooth. By using the generalized projection operator, we prove a strong convergence theorem which does not require the prior knowledge of the Lipschitz constant of cost operator. We further applied our result to constrained convex minimization problem, convex feasibility problem and infinite family of equilibrium problems. Our results improve and complement related results in 2-uniformly convex and uniformly smooth Banach spaces and Hilbert spaces.

Abstract:
The objective of the paper is to study the geometrical
properties of the class B(λ, t).
For which we have proved that the radius
is optimal ,(i.e)
the number
cannot be replaced by a larger one. Additionally, the graphs for various values of t and
λ are compared in order to study the sharpness of the coefficient bounds.

Abstract:
An efficient double-projection method, with a new search strategy, is designed for solving variational inequalities in real Hilbert spaces with pseudo-monotone cost operator. Our proposed method uses a computationally inexpensive simple line search procedure based on local information of the operator and very weak conditions of parameters to obtain larger step sizes. A description of the algorithm along with its weak convergence is provided without assuming Lipschitz continuity. Also, a modification to the proposed method is presented, wherein the second projection onto the closed and convex subset is replaced with the one onto a subgradient half space. Numerical experiments and comparisons with related methods demonstrate the reliability and benefits of the proposed schemes.
