M. Ghayasuddin,


Abstract
: 

In this paper, we introduce a new class of generalized HermiteEuler and HermiteGenocchi polynomials and derive some symmetric identities by applying the generating functions. Also, we obtain some potentially useful relations for the Bernoulli polynomials, Euler polynomials, power sum, alternating sum and Genocchi
numbers. These results extend some known summations and identities of generalized HermiteEuler and HermiteGenocchi polynomials studied by Dattoli et al. [3],
Pathan and Khan [9], Khan [5]. 






Some transcendence results from a harmless irrationality theorem


Fabio Menezes de Souza Lima,


Abstract
: 

The arithmetic nature of values of some functions of a single variable, particularly, $\sin{z}$, $\cos{z}$, $\sinh{z}$, $\cosh{z}$, $e^z$, and $\ln{z}$, is a relevant topic in number theory. For instance, all those functions return transcendental values for nonzero algebraic values of $z$ ($z \ne 1$ in the case of $\ln{z}$). On the other hand, not even an irrationality proof is known for some numbers like $\,\ln{\pi}$, $\,\pi + e\,$ and $\pi \, e$, though it is wellknown that at least one of the last two numbers is irrational. In this note, I first generalize the last result, showing that at least one of the sum and product of any two transcendental numbers is transcendental. I then use this to show that, given any nonnull complex number $\,z \ne 1/e$, at least two of the numbers $\,\ln{z}$, $\,z +e\,$ and $\,z \, e\,$ are transcendental. I also show that $\,\cosh{z}$, $\sinh{z}\,$ and $\,\tanh{z}\,$ return transcendental values for all $\,z = r \, \ln{t}$, $\,r \in \mathbb{Q}$, $r \ne 0$, $\,t\,$ being any transcendental number. The analogue for common trigonometric functions is also proved. 






Existence of Solutions to a Threepoint Entrainment of Frequency Problem


Mesliza Mohamed,


Abstract
: 

In this paper, we deal with the existence of solutions to the frequency problem of a perturbed system, x−A(t)x = εf(x,sinwt, coswt, ε) with threepoint boundary condition. The topological technique is used to obtain existence theorem. Two examples are given to illustrate our results.







Ascertainment of The Certain Fundamental Unit in a Speciﬁc Type of Real Quadratic Fields


Zubair Nisar,


Abstract
: 

The aim of the paper is to classify the real quadratic number fields Q(√ d) having specific form of continued fraction expansions of algebraic integer wd and is to determine the general explicit parametric representation of the fundamental unit d for such real quadratic number fields where d ≡ 2,3(mod4) is a square free positive integer. Also, Yokoi’s dinvariants nd and md will be calculated in the relation to continued fraction expansion of wd for such real quadratic fields.

Uniform Exponential Stability for Time Varying Linear Dynamic Systems over Time Scales


Syed Omar Shah,


Abstract
: 

This paper proves the uniform exponential stability of the time varying linear dynamic system $x^\Delta(r)=G(r)x(r),\ r \in \overline{T}$ in terms of boundedness of solution of the following Cauchy problem:
\begin{equation*}
\left\{
\begin{split}
W^{\Delta}(r)&=G(r)W(r) + \omega(r), \ 0\leq r \in \overline{T}, \ W(0) &= v_0,
\end{split}
\right.
\end{equation*}
where $\overline{T}$ denotes time scale, $G(r)$ is a matrix valued function, $\omega(r)$ is a bounded function on $\overline{T}$ and $v_0 \in \mathbb{C}^m$. In this note we prove the results that have the above result as an immediate corollaries. 






On cyclic (α,β)admissible generalized contraction mappings in generalized metric spaces


Eskandar Ameer,


Abstract
: 

The aim of this paper is to present new fixed point results in the framework of Branciari metric spaces. Some examples are presented to support the results proved herein. These results unify, generalize and complement the results of Jleli and Samet [J. Inequal. Appl. 2014, Article ID38(2014)]. We also provide an example of our result, where the comparable result in the existing literature is not applicable. As an application of our results, we obtain a fixed point results involving a cyclic mapping, not necessarily continuous. 






Two Dimensional Laplace Transforms for Solving Systems of Fractional Partial Differential Equations


M.R. Masomi,


Abstract
: 

Abstract
In this work, the authors implemented two dimensional Laplace transform to solve certain in homogenous sub ballistic fractional PDE and homogeneous systems of time fractional heat equations which is a generalization to the problem of thermal effects on fluid flow and also the problem of the effect of a uniform overburden on the passage of a thermal wave and the temperatures in the underlying rock. Constructive examples are also provided.
