## Edikan E. Akpanibah and Bright O. Osu, Portfolio Strategy for an Investor with Stochastic Premium Under Exponential Utility via Legendre Transform and Dual Theory, Volume 2017, Number 6, Pages 27-35, 2017

Abstract: We investigate the optimal investment strategies of an insurance company. We assume that the rates at which premiums are paid to insurance companies are stochastic, the total claims are modeled by a compound Poisson process, we assume that surplus of the insurance company is invested...

Abstract: It is known that a homeomorphism between two topological spaces preserves all the topological properties such as connectedness and compactness. To a map of spaces we can associate a homomorphism of groups such that compositions of maps yield compositions of homomorphisms of groups. Then any...

## Bochar Laarabi and Bouchaib Radi, A Two-Phase Heuristic Method for Solving Team Orienteering Problem, Volume 2017, Number 6, Pages 10-19, 2017

Abstract: The Team Orienteering Problem $(TOP)$ is an catchy variant of the Vehicle Routing Problem $(VRP)$. The aim at maximizing the total amount of profit collected by a fleet of vehicles while not exceeding a predefined travel cost limit on each vehicle. In this paper,we propose...

## Surendra Kumar Tiwari and Kaushik Das, Cone Metric Spaces and Fixed Point Theorems for Generalized T-Reich Contraction with c-Distance, Volume 2017, Number 6, Pages 1-9, 2017

Abstract: A new concept of the c-distance in cone metric spaces has been introduced by Cho et al. [8] in 2011. Recently, Fadail et al. [24] in 2017 introduced the $T$-Reich contraction under the concept of $c$-distance in cone metric spaces and proved uniqueness fixed point...

## Bazuaye F.E and Osisiogu A.U, A New Approach to Constructing Extended Exponential General Linear Methods for Initial Value Problems in Ordinary Differential Equations, Volume 2017, Number 5, Pages 44-54, 2017

Abstract: This paper focuses on a new extension approach for the construction of Exponential General Linear Methods. These methods are related to Butcher, Calvo and Palencia and Osisiogu and Bazuaye Methods, but, in contrast to the later, we make use of higher terms of the exponential and related...

## S. R. Barbhuiya, (∈, ∈ ∨q)-Interval-Valued Fuzzy Prime Ideals of BCK -Algebras, Volume 2017, Number 5, Pages 31-43, 2017.

Abstract: The notion of $(\in,\in \vee q)$-interval-valued fuzzy prime ideals in commutative BCK-algebras is introduced. Some characterization theorems in -interval-valued fuzzy prime ideals in commutative BCK-algebras are derived. Also we study relation between -interval-valued fuzzy prime ideal and -interval-valued fuzzy level prime ideals. Characterization of interval-valued fuzzy set to...

## A. G. Shannon and Kenny Pruitt, Functional Difference Equations, Volume 2017, Number 5, Pages 22-30, 2017.

Abstract: The purpose of this paper is to generalize some results of Horadam and to extend some identities due to Carlitz in the context of functional difference equations. It includes an operator which yields a type of Appell-set criterion. Generalizations of Simson’s identity occur as by-products and these...
