On the Hamiltonian reduction of geodesic motion on SU(3) to SU(3)/SU(2)
نویسنده
چکیده
Abstract The reduced Hamiltonian system on T∗(SU(3)/SU(2)) is derived from a Riemannian geodesic motion on the SU(3) group manifold parameterised by the generalised Euler angles and endowed with a bi-invariant metric. Our calculations show that the metric defined by the derived reduced Hamiltonian flow on the orbit space SU(3)/SU(2) ≃ S5 is not isometric or even geodesically equivalent to the standard Riemannian metric on the five-sphere S5 embedded into R6.

Haraz-Ghareh Su is one of the seven sub-basins of the Caspian basin, located on the southern shores of the Caspian Sea, and as such, is in danger of water crisis due to absence of proper systematic policy and strategy. In this study, the pressure factors on the Haraz-Ghareh Su water resources were identified using DPSIR model. Then, the pressure parameters on the freshwater resources in the Cas...

Hydrogeochemistry of hydrothermal waters from Salams magma chamber: Case study of Isti Su hot spring, NW of Iran
The Isti Su hot spring is located in southeast of Salmas, in Western Azerbaijan, Iran. The area is a small part of Sanandaj-Sirjan geological zone which hosts many hot springs. The magma chamber of Salmas region is the main heat source of the hot springs in Isti Su area. Abundant rainfall and relatively long duration of snowfall as well as several deep faults in the area create the best conditi...
