Download e-book for kindle: Differential Geometry, Gauge Theories and Gravity by M. Göckeler, T. Schücker

Utilizing a self-contained and concise remedy of recent differential geometry, this e-book might be of significant curiosity to graduate scholars and researchers in utilized arithmetic or theoretical physics operating in box concept, particle physics, or normal relativity. The authors start with an simple presentation of differential varieties.

Download e-book for kindle: Semi-Riemannian Geometry With Applications to Relativity, by Barrett O'Neill

This e-book is an exposition of semi-Riemannian geometry (also known as pseudo-Riemannian geometry)--the examine of a gentle manifold supplied with a metric tensor of arbitrary signature. The primary exact situations are Riemannian geometry, the place the metric is confident convinced, and Lorentz geometry. for a few years those geometries have constructed nearly independently: Riemannian geometry reformulated in coordinate-free model and directed towards worldwide difficulties, Lorentz geometry in classical tensor notation dedicated to common relativity.
