Topological Methods in Nonlinear Analysis - quarterly international journal is published by the Juliusz Schauder University Centre for Nonlinear Studies with the assistance of the Nicolaus Copernicus University in Toruń.
TMNA is preparing a Memorial Issue dedicated to our recently deceased friend and colleague Marek Burnat. Professor Burnat was one of the founders of the Schauder Center in Toruń and the journal Topological Methods in Nonlinear Analysis. On behalf of the Editors of TMNA we invite submissions of articles to this issue, which would appear during the second part of 2017. The member of the Editorial Committee, Professor Wojciech Zajączkowski will be a Special Editor of the issue.
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 2015 = 0.717 and 5-year IF = 0.837.
The central topics are:
- nonlinear ordinary and partial differential equations and systems, boundary value problems, nonlinear integral equations, equations of mathematical physics;
- differential inclusions, stochastic equations and systems, functional-differential equations, nonlinear analysis methods in discrete mathematics;
