Fixed Point Theory in Various Spaces; Theory, Methods and Applications

Over the past few decades, fixed point theory has been developed into a basic and useful tools for different branches of both pure and applied mathematics. In particular, it may be discussed as an essential subject of nonlinear functional analysis. Moreover, fixed point theory is one of the important tools to solve many problems in physics and engineering such as: the existence of solutions to integral equations, differential equations, matrix equations, dynamical systems, models in economy, game theory, fractals, graph theory, computer science and many other subjects.

The Editor-in-Chief of Journal of Linear and Topological Algebra has decided to publish two special issues about fixed point theory in various spaces and Its application. Accordingly, all interested researchers are invited to contribute to these special issues. Authors can submit their manuscripts through the Manuscript Tracking System at

When submitting your paper, be sure to specify that the paper is a contribution for the Special Issue of Fixed Point Theory in Various Spaces. All papers will be reviewed according to the high standards of JLTA. Accepted papers will be published online individually, before print publication.

Journal of Linear and Topological Algebra (JLTA) is indexed/abstracted in Mathematical Reviews; Zentralblatt MATH; Digital Mathematics Registry; Directory of Open Access Journals (DOAJ); Scientific Information Database; Google Scholar; Copernicus and etc. Also, JLTA apply for being indexed Clarivate Analytics (ISI) productions in due time.

Main topics of interest are (but not restricted to):

  • History and Topological aspects of fixed point theory
  • Fixed and Periodic point results in various metric spaces and their applications
