Abstract

This award is concerned with a broad range of research in gravitational physics. Some of the research deals with issues that have arisen in attempts to formulate a quantum theory of gravity, such as issues involved in the calculation of the "wavefunction of the universe". Other projects involve investigation of the effects of strong gravitational fields on the quantum properties of matter, such as the extent to which certain positive energy properties continue to hold in the presence of gravity. Yet other research projects concern the nature and properties of classical gravitational fields in the theory of general relativity. Some of the latter projects---such as the determination of forces on bodies associated with their emission of gravitational radiation---have direct implications for astrophysics and cosmology. Although the proposed research includes a wide range of topics in a number of different areas, there is a common theme to the main goals of the research: To obtain a deeper understanding of the mathematical and physical properties of the gravitational field as described by the theory of general relativity, and to make progress toward the formulation and development of a quantum theory of gravity. The development of a quantum theory of gravity is currently at the forefront of fundamental research in theoretical physics.
