Abstract:
Systems of partial differential equations (PDE) and ordinary differential equations (ODE) are studied from
the point of view of Dynamical systems methods. Many problems from biology, chemistry, mechanics,
control, information transmission, economics and other fields are changing in time and so they can be
described by different types of Dynamical systems. It is well understood that taking into account delay
effects (memory) makes the mathematical models more realistic. We are interested in developing
approaches for study of local and long-time asymptotic behavior of different types of solutions to delay
PDEs and ODEs. An important type of delay is the state-dependent one. This type of delay seems to be
the most natural from the point of view of applications (it also includes the case of constant delay) and
simultaneously the most difficult from mathematical point of view. The main goal of the project is
therefore to study basic properties of such systems, including a new type of dynamical state-dependent
delay and coupled differential-algebraic systems of delay equations.
