Title : Stability of a Quadratic Functional Equation Originating From Sum of the Medians of a Triangle in Fuzzy Ternary Banach Algebras: Direct and Fixed Point Methods

Abstract: In this paper, we obtain the solution in vector space and the generalized Ulam-Hyers stability of the ternary quadratic homomorphisms and ternary quadratic derivations between fuzzy ternary Banach algebras associated to the quadratic functional equation \begin{align*} f\left(\frac{x+y}{2}-z\right)+f\left(\frac{y+z}{2}-x\right)+f\left(\frac{z+x}{2}-y\right)=\frac{3}{4}\left(f(x-y)+f(y-z)+f(z-x)\right) \end{align*} originating from sum of the medians of a triangle by using direct and fixed point methods. An application of this functional equation is also studied.

Keywords: Fuzzy ternary Banach algebra, Quadratic functional equation, Ulam - Hyers stability, Fixed point method.

Title : Coincidence Point Theorem Under Mizoguchi-Takahashi Contraction on Ordered Metric Spaces With Application
Country : India
Authors : Bhavana Deshpande || Amrish Handa || Chetna kothari

Abstract: We construct coincidence point result for $g$ -non-decreasing mappings satisfying Mizoguchi-Takahashi contraction on ordered metric spaces. By using our result, we formulate a coupled coincidence point result for generalized compatible pair of mappings $F,$ $ G:X^{2}\rightarrow X.$ We give an example and an application to integral equation to show the usefulness of the obtained results. Our results generalize, modify, improve and sharpen several well-known results.

Keywords: Coincidence point, coupled coincidence point, generalized Mizoguchi-Takahashi contraction, ordered metric space, O-compatible, generalized compatibility, $g$-non-decreasing mapping, mixed monotone mapping.

Title : A Multiple Linear Regression Approach for the Analysis of Stress Factors of Faculty in Higher Educational Institutions
Country : India
Authors : P.Ramesh Reddy || Dr.K.L.A.P.Sarma

Abstract: One of the fast growing sectors in India and abroad is an education sector. This sector masses highly qualified and committed faculty to enhance the quality of education and also to equip the student to meet demand of the industry. In this process faculty has to face many challenges and difficulties to meet the requirements of the education sector. The objective of the present study is under taken to address the effects of different inducing stress factors on job stress of the faculty in higher educational institutions of chittoor district, Andhra Pradesh. Instrument was used in order to get the responses from higher education institutions faculty to achieve the above stated objective. Multiple linear regression and ANOVA were used to analyze the data collected from 500 respondents. Different models were suggested to different categories of faculty members in higher educational institutions to measure their occupational stress and also identified highly contributed factors related to job stress to prevent professional burnout of faculty in higher education.

Keywords: Faculty, Job stress, Multiple linear regression, ANOVA, Higher education.

Title : Rainbow Connection Number of Sunlet Graph and its Line, Middle and Total Graph
Country : India
Authors : K.Srinivasa Rao || R.Murali

Abstract: A path in an edge−colored graph is said to be a rainbow path if every edge in the path has a different color. An edge colored graph is rainbow connected if there exists a rainbow path between every pair of its vertices. The rainbow connection number of a graph G, denoted by $rc(G)$, is the smallest number of colors required to color the edges of G such that G is rainbow connected. Given two arbitrary vertices u and v in G, a rainbow $u-v$ geodesic in G is a rainbow $u-v$ path of length $d(u, v)$, where $d(u, v)$ is the distance between u and v. G is strongly rainbow connected if there exist a rainbow $u-v$ geodesic for any two vertices u and v in G. The strong rainbow connection number of G, denoted by $src(G)$, is the minimum number of colors required to make G strongly rainbow connected. SyafrizalSyet. al. in \cite{2} proved that, for the sunlet graph $S_n$, $rc(S_n)=src(S_n)=\lfloor\frac{n}{2}\rfloor+n$ for $n\geq2$. In this paper, we improve this result and showthat $rc(S_n)=src(S_n)=\left\{ \begin{array}{ll} n, & \hbox{if n is odd;} \\ \frac{3n-2}{2}, & \hbox{if n is even.} \end{array} \right.$ We also obtain the rainbow connection number and strong rainbow connection number for the line, middle and total graphs of $S_n$

Keywords: Rainbow connection number, sunlet graph, line graph, middle graph and total graph.
