On a Geometry Associated with Free Pseudo-Product Fundamental Graded Lie Algebras
1--9--2 Masakae, Otaru 047-0003, Japan
We calculate the prolongations of the underlying fundamental graded Lie algebras of free pseudo-product fundamental graded Lie algebras. Also we show that the Lie algebra of infinitesimal automorphisms of a differential system associated with the Hilbert-Cartan equation in a wider sense is isomorphic to the prolongation of the underlying fundamental graded Lie algebra of some free pseudo-product fundamental graded Lie algebra.
Keywords: Pseudo-product graded Lie algebra, prolongation, Hilbert-Cartan equation.
