Interview with accountant and Army veteran Frederick R. Freeman. The interview includes Freeman's personal experiences about the European Theater during the World War II, basic training, advanced infantry training, initial combat on the front lines in France, survival techniques under combat conditions, the Ardennes Offensive, and the Battle of the Bulge. Freeman also talks about the effects of combat losses and acclimation of individual replacements, his bout with combat exhaustion and reassignment to a replacement depot as a clerk, his participation in the Army of Occupation, and postwar adjustments to civilian life.

Exceptional groups, symmetric spaces and applications (open access)

Exceptional groups, symmetric spaces and applications

In this article we provide a detailed description of a technique to obtain a simple parameterization for different exceptional Lie groups, such as G{sub 2}, F{sub 4} and E{sub 6}, based on their fibration structure. For the compact case, we construct a realization which is a generalization of the Euler angles for SU(2), while for the non compact version of G{sub 2(2)}/SO(4) we compute the Iwasawa decomposition. This allows us to obtain not only an explicit expression for the Haar measure on the group manifold, but also for the cosets G{sub 2}/SO(4), G{sub 2}/SU(3), F{sub 4}/Spin(9), E{sub 6}/F{sub 4} and G{sub 2(2)}/SO(4) that we used to find the concrete realization of the general element of the group. Moreover, as a by-product, in the simplest case of G{sub 2}/SO(4), we have been able to compute an Einstein metric and the vielbein. The relevance of these results in physics is discussed.
