This text offers a geometrical treatment of observational cosmology from the concepts of the theory of dynamical systems. Since mathematical techniques are not a familiar tool in this field, a summary of the ideas of differential geometry, ergodic theory and catastrophe theory is included.

This text provides a complete survey of the astrophysics of planetary nebulae, including theory and observations. It covers various subjects, including various aspects of emission lines, ionization equilibrium, electron temperature, and the ultraviolet and the continuous spectra.

This monograph contains an overview of classical dynamics, providing a solid basis on which to build an understanding of the theory of interplanetary flights. The treatment of the topic is based on both historical and topical perspectives.
