Clebsch–Gordan and Racah Coefficientsohomology. We construct the external and internal product of relative and absolute characters and show that relative differential cohomology is a right module over the absolute differential cohomology ring. Finally we construct fiber integration and transgression for relative differential characters.

Differential Characters and Geometric Chains,ess of differential cohomology (up to unique natural transformation) is proved by deriving an explicit formula for any natural transformation between a differential cohomology theory and the model given by differential characters. Fiber integration for fibers with boundary is treated in the context

These attributes are affected by both intra- and extra-cellular processes resulting in the emergence of complex spatial and temporal behavio

Seeking a response to the unexpected and unwelcome news in the autumn of 1949 that the Soviet Union had exploded an atomic device, and with it the four-year American atomic monopoly, U.S. policymakers stood at a crossroads. One path was chosen on January 31, 1950, after four months of intense, some
