Introduction ot Asteroseismology

This lecture gives an introduction to theoretical asteroseismology. It is neither a review nor is exhaustive. It attends to give to Master and PhD students an idea on why we are able to interpret asteroseismic observations in terms of internal structure and evolutionary stages of the stars. The fundation and basic understanding of asteroseismology rely on well-known physical principles and mathematical tools. Nervetheless there are many issues that still ought to be elucidated. This resquires data of higher and higher quality for an increasing number of stars. This is the goal of future space missions to provide with such data sets
