Difference in the number of operators between coupled and uncoupled basis for the general SU(n) Lie algebra

For the cases of irreducible representation, the complete set of operators necessary to specify uniquely the states. There are two ways of representing the state, using uncoupled and coupled basis. Here we discuss, how the number of operators for the cases of coupled and uncoupled basis changes as well as their difference with the increase of dimension. For higher dimensional groups this number difference changes systematically.

Neutron Disks Around Black Holes

We study nucleosynthesis in low accretion rate hot advective flows around black holes. We find that matter is generally photo-dissociated into protons and neutrons inside the disk. These neutrons stay around black holes for longer time because they are not coupled to magnetic fields while the protons accrete into the hole. We find the nature of the resulting neutron disks and estimate the rate at which these disks contaminate the surroundings.
