The aim of the session is to make a focus on some recent trends on nonlinear problems of different type, e.g., ordinary, partial differential equations and inclusions, as well as difference equations. It will be emphasized how the various methods and techniques -- of variational, topological or set-valued nature -- can be employed, separately or in combination, for studying the existence, the multiplicity and some qualitative properties of the solutions. Topics involving equations driven by nonlinear differential operators, or with the presence of singular terms, are welcome.

Non-Linear Difference Equations
Garyfalos Papaschinopoulos
Democritus University of Thrace, Greece
gpapas@env.duth.gr
Christos J. Schinas
Democritus University of Thrace
cschinas@ee.duth.gr
This session deals with non-linear difference equations and systems of non-linear difference equations i.e. difference equations with exponential terms, rational difference equations, etc...
Non-linear difference equations have numerous potential applications in Biology. The existence and uniqueness of equilibria, the attractivity and the global asymptotic stability of the equilibria will be studied. Centre manifold theory and other techniques can be used for this goal.

Cardiovascular diseases still remain the leading cause of death in developed countries. A deeper understanding of the physiopathologies associated to diseases like atherosclerosis, thrombosis or aneurysm growth and its eventual rupture has a significant impact in terms of social well-being and reduction of healthcare costs.
Based on modern, high-resolution, medical imaging techniques, the development of spatially realistic mathematical models for cardiovascular diseases, leads to complex systems of partial differential equations describing heterogeneous processes of multiscale nature. These coupled models require highly integrated and efficient numerical algorithms and high performance computing techniques for their simulation.
This special session will bring together open questions and recent advances in this topic.
Multi-scale Modeling and Homogenization of Partial Differential Equations
Hari Shankar Mahato
IIT Kharagpur, India
hsmahato@maths.iitkgp.ac.in
In this session, we focus on the multi-scale modeling of different types of physical phenomena. These phenomena usually give rise to partial differential equations. We will look into the analysis part of these PDEs such as existence and uniqueness of solution and we will also learn about different upscaling methods to homogenize these PDEs from micro-scale to macro-scale.
Recent Progress in the Theory of the Navier-Stokes and Related Equations

The Navier-Stokes and related equations have already for many decades been a subject of great interest of mathematicians and physicists.
Recently developed theoretical methods and tools enabled to formulate new criteria for uniqueness, stability, long time behavior and regularity of weak and mild solutions. New results also concern multi-component flows, interaction between fluids and immersed bodies and many other states or processes.
The special session therefore aims at bringing together researchers from various countries, working in these or related fields, and to initiate or maintain fruitful discussions and cooperations.
