# Events of CI²MA

Description: Advanced mathematical models for biological phenomena that evolve in space and time, such as infectious diseases, dynamics of populations, ecological systems, invasions, predator-prey systems, food chains, movement of bacteria, chemotaxis, and pattern formation, can be formulated in terms of a partial differential equation or a system of such equations. Such a mathematical model relates the rate of change of a quantity (typically, the density of a species or the concentration of a substance) at a given position with the value and spatial gradients of the same and other unknowns. Typical ingredients include spatially heterogeneous environments, the variability of climate due to marked different seasons, birth and death processes, and effects of human inteference such as harvesting, vaccination, and travel activity. It is the purpose of this course to provide an introduction to the mathematical theory of selected partial differential equations that arise in this context, including creating familiarity with the types of PDE appearing in biology and the underlying modeling strategies; the analysis of parabolic systems of equations arising in this context; the study of weak solutions; an exploration of the phenomenon of finite time blow-up and chemotaxis; hyperbolic equations; and a simple kinetic equation.
