Generating infinite-dimensional algebras from loop algebras by expanding Maurer-Cartan forms
It is shown that the expansion methods developed in de Azcarraga et al.[Nucl. Phys. B 662, 185 (2003); Class. Quantum Grav. 21, S1375 (2004)]; can be generalized so that they permit to study the expansion of algebras of loops, both when the compact finite-dimensional algebra and the algebra of loops have a decomposition into two subspaces.
