Topological Methods in Nonlinear Analysis - quarterly international journal is published by the Juliusz Schauder University Center for Nonlinear Studies at the Nicolaus Copernicus University in Toruń.
Call for papers
The special issue of Topological Methods in Nonlinear Analysis will be dedicated to the memory of Professor Kazimierz Goebel, an outstanding scientist, teacher of generations of mathematicians in Poland and around the world, a former Chairman of the Scientific Council of the Schauder Center and a member of the Editorial Committee of the Topological Methods in Nonlinear Analysis journal, a person of great merit to our community.
Professor Goebel has profoundly contributed to the metric fixed point theory and geometry of Banach spaces. His co-author book with W. A. Kirk, Topics in metric fixed point theory, Cambridge Studies in Advanced Mathematics, 28. Cambridge University Press (1990), is a staple and much cited monography in the subject.
The issue will be co-edited by the special guest-editors Stanisław Prus and Łukasz Piasecki, who invite submissions of original research papers. Submissions will be considered via a peer review process.
TMNA publishes research and survey papers on a wide range of nonlinear analysis, giving preference to those which employ topological methods. Papers in topology which are of interest in nonlinear problems may also be included.
The current impact factors are IF 2021 = 0.869.
