Set Theory for Physicists

Nicolas A Pereyra


This book provides a rigorous, physics-focused introduction to set theory that is geared towards natural science majors. The science major is presented with a robust introduction to set theory, which concentrates on the specific knowledge and skills that will be needed for calculus and natural science topics in general.

About Editors

Nicolas A Pereyra pursued his undergraduate studies in physics in Caracas at the Universidad Central de Venezuela, where he graduated in 1991. Following this, he studied physics at the University of Maryland at College Park where he obtained his MS and PhD in 1995 and 1997. Currently, Pereyra is an associate professor in astrophysics at the Physics and Astronomy Department of the University of Texas Rio Grande Valley. His research work has largely focused on the development of computational models of physical systems, and he is presently working on the development of computational models of accretion disk winds in QSOs.
