Abstract
In this paper we compute cyclic and Hochschild homology of the universal envelope of the Yang–Mills Lie algebra . We also compute Hochschild cohomology with coefficients in , considered as a bimodule over itself.
The result of the calculations depends on the number of generators of . The semidirect product acts by derivations upon . One of the important consequences of our results is that if then the Lie algebra of outer derivations of coincides with .
