An account of our understanding of the behaviour of hot dense matter in the Universe. The first part of the text derives the nuclear equations of state of neutron star matter in the framework of relativistic field theory. The second part constructs models of rapidly rotating neutron stars (pulsars) in the framework of general relativity theory using the equations of state derived earlier as input data. Predictions from these models are then compared with astrophysical observations.

Offers an account of four dimensional simple supersymmetry and supergravity. This book covers algebraic aspects of supersymmetry and the concepts of superspace and superfield. It presents classical and quantum superfield theory and the superfield formulation of supergravity. It concludes with the theory of effective action in curved superspaces.

Although gravity is the dominant force of nature at large distances (from intermediate scales to the Hubble length), it is the weakest of forces in particle physics, though it is believed to become important again at very short scales (the Planck length). The conditions created in particle accelerators are similar to those at the time of the early universe. While particle physics offers insight to early universe physics, there is a need to understand gravity at extremes of large and short distances to further understand cosmology and the development of the universe.
