https://doi.org/10.22105/riej.2022.352994.1326

Abstract
  Mindset means mental attitude. Methodology means a system of methods used in a particular area of study. If one studies any textbook in industrial engineering, one reads about various optimization methods. Hence it is natural to assume that industrial engineering is a methodology. However, this paper ...  Read More

Volume 8, Issue 1 , April 2019, , Pages 77-88

https://doi.org/10.22105/riej.2019.159539.1065

Abstract
  This paper deals with the number theoretic properties of non-unit elements of the ring Zn. Let D be the set of all non-trivial divisors of a positive integer n. Let D1 and D2 be the subsets of D having the least common multiple which are incongruent to zero modulo n with every other element of D ...  Read More

Fixed point theorems of LW-type Lipschitz cyclic mappings in complete B-metric-like spaces

Sh. Weng; Y. Zhang; D. P. Wu

Volume 7, Issue 2 , September 2018, , Pages 136-146

https://doi.org/10.22105/riej.2018.143285.1051

Abstract
  The research of Fixed Point Theorems (FPTs) plays an important role in nonlinear analysis. It is of great theoretical significance and profound application value to study general abstract theory in a B-Metric-Like Space (BMLS). So, it is an important topic to study the Fixed Point Theory (FPT) in a BMLS. ...  Read More
