%0 Journal Article %A Campoamor Stursberg, Otto-Rudwig %T Intrinsic formulae for the Casimir operators of semidirect products of the exceptional Lie algebra G2 and a Heisenberg Lie algebra %D 2004 %@ 0305-4470 %U https://hdl.handle.net/20.500.14352/50699 %X We showthat the Casimir operators of the semidirect productsG2−→⊕2�(a,b)⊕�(0,0)h of the exceptional Lie algebraG2 and a Heisenberg algebra h can be constructed explicitly from the Casimir operators of G2. %~
