Topic: Origin and Propagation of UHE Particles
Lecturer: M. Teshima

In this lecture, the origin and the propagation of UHECRs will be discussed. So far many models are proposed to explain UHECRs.  We would like to discuss some important models from the experimental view. To understand the relation between the observables (energy spectrum, anisotropy and chemical composition) and the origin of UHECRs, we also need to discuss the effect of the propagation and the cascade of UHECRs in the universe.
