Air transportation in the Philippines Air transportation in the Philippines goes back to the early days of aviation prior to World War II, during the American colonial period of the Philippines. Currently, the Philippines has several registered airline companies, but they are mostly chartered. There are two main domestic airline groups doing business as Philippine Airlines and Cebu Pacific, with AirAsia
Lie group–Lie algebra correspondence simply denoted by formula_77.) The homomorphisms theorem (mentioned above as part of the Lie group-Lie algebra correspondence) then says that if formula_78 is the simply connected Lie group whose Lie algebra is formula_56, "every" representation of formula_56 comes from a representation of "G". The assumption that "G" be simply connected is essential. Consider, for example, the rotation group SO(3), which is not simply connected. There is one irreducible representation of the Lie algebra in each dimension, but only the odd-dimensional representations of the Lie algebra come from representations of the group. (This observation is related to the distinction between integer
