Lecture Notes in Physics. Einstein’s Field Equations and Their Physical Implications.

Lecture Notes in Physics. Selected Essays in Honour of Jürgen Ehlers. The essays are devoted to exact solutions and to the Cauchy problem of the field equations as well as to post-Newtonian approximations that have direct physical implications. Further topics concern quantum gravity and optics in gravitational fields. Bibliographic Information.

Jürgen Ehlers was born on December 29,1929 in Hamburg. He attended public schools from 1936 to 1949, and went on to study physics, mathematics, and philosophy at Hamburg University from 1949 to 1955. In physics, a duality symmetry exists whenever the laws of physics remain unchanged under the exchange of seemingly different physical quantities. The best-known example is the duality between the electric field E and the magnetic field field B in source-free electrodynamics, where the replacement E. o.

In the Einstein field equations we now carry out the transition to the limit of nonrelativistic mechanics. As was stated in § 87, the assumption of small velocities of all particles requires also that the gravitational field be weak. The expression for the component g00 of the metric tensor (the only one which we need) was found, for the limiting case which we are considering, in § 87: g00 1+2φc2.

Although the Einstein field equations were initially formulated in the context of a four-dimensional theory, some theorists have explored their consequences in n dimensions. The equations in contexts outside of general relativity are still referred to as the Einstein field equations. The vacuum field equations (obtained when T is identically zero) define Einstein manifolds. Despite the simple appearance of the equations they are actually quite complicated.

Ehlers' doctoral work was on the construction and characterization of solutions of the Einstein field equations. In physics, duality means that two equivalent descriptions of a particular physical situation exist, using different physical concepts.

In physics, duality means that two equivalent descriptions of a particular physical situation exist, using different physical concepts. This is a special case of a physical symmetry, that is, a change that preserves key features of a physical system.
