-
As is the case every academic year, the Center organizes a series of seminars, given by faculty members of the University of Patras, visiting faculty from other universities and graduate students who wish to present informally results related to their Master's or Ph. D. thesis' work. The Speakers generally come from different disciplines and are asked to present their work in a way that would be understandable to a rather broad scientific audience. The only requirement is that their topic be relevant to a problem in the area of Nonlinear Systems, which is of mathematical, physical, biological, technological, economic or social interest.
If there is sufficient interest, the lectures will be given in English!
Second Semester
The Mathematics Department, and in particular the Division of Applied Analysis is organizing this semester a series of seminars which are of particular interest to those working with nonlinear differential equations.
Tuesday June 20:
10:00 - 11:30: Room 342 Math/Biol build.
Prof. Giorgio Turchetti, Dept of Physics, University of Bologna
Mathematical Models in Biology: Immune System and Aging
Biological systems exhibit many space-Time scales. Large scale models are based on population dynamics and the influence of environment is described by deterministic or stochastic forcing terms. In the case of the immune system the evolution of the virgin and memory T lymphocytes is considered under the action of a chronic antigenic stress. The main properties of the proposed Langevin equation and of the related Ulembeck process are outlined.
The model describes the decrease of the virgin T cell compartment and provides survival curves, assuming that the compartment depletion is a mortality marker. A microscopic model for the clonal expansion under the action of the acute antigenic attack and chronic stress is outlined.
Tuesday June 20:
12:00 - 1:30: Room 342 Math/biol build.
Prof. N. Buric , Dept. of Physics, University of Beograd
Phenomenological Model of Immune Response to Immunogenic Tumors
Immune response constitutes a set of complicated processes in a quite complex system. Extreme complexity of the system, and quite partial knowledge of the basic reactions and processes involved, justifies a phenomenological approach to the modeling of the systems dynamics. We proposed and analyzed a model of the immune response to immunogenic tumor which has quite simple formulation and could have sufficiently complicated dynamics. The model gives consistent predictions for the values of the relevant parameters estimated from real data.

Geometrical Aspects in Intense Particle Beam Dynamics
High intensity accelerators are facing new applications for neutron spectroscopy, wastes transmutation and inertial fusion. Mathematical modeling is based on Hamiltonian dynamics, however the relevance of Coulomb interactions requires a statistical approach. Neglecting the collisions, the Poisson-Vlasov equations describe the evolution of the system and some analytic solutions such as KV are known. The mathematical properties of the envelope equations, they satisfy, are outlined.
Given the self consistent electric field, the single particle dynamics is investigated by the frequency analysis. The resonance structure is found and the chaotic regions appear to be enhanced by the presence of mismatch oscillations and lattice non linearities. Comparison with the simulations is discussed.

Self-Similarity and Transport in 2 Degree of Freedom Hamiltonian Systems
The phase portrait of a typical Hamiltonian dynamical system is a complicated fractal with strong evidence of self-similarity. This fractal structure is responsible for the difficulties in the development of a computationally effective theory of transport in the phase space. However, the self-similarity of such fractals could be used to encode them in terms of continuous and smooth functions. This is the basic idea in the method of modular smoothing. We illustrate the method by discussing its applications for the calculations of KAM tori, critical functions and actions of periodic orbits.
