A note on free presentations and residual nilpotence

Sven Möller
2021 arXiv   pre-print
Scheithauer showed that there are exactly ten Borcherds-Kac-Moody algebras whose denominator identities are completely reflective automorphic products of singular weight on lattices of square-free level  ...  These belong to a larger class of Borcherds-Kac-Moody (super)algebras Borcherds obtained by twisting the denominator identity of the Fake Monster Lie algebra.  ...  Let ν be of square-free order m in M 23 .

Anosov Automorphisms of Nilpotent Lie Algebras [article]

Tracy L. Payne
2008 arXiv   pre-print
Each matrix A in GL_n(Z) naturally defines an automorphism f of the free r-step nilpotent Lie algebra on n generators.  ...  We study the relationship between the matrix A and the eigenvalues and rational invariant subspaces for f. We give applications to the study of Anosov automorphisms.  ...  We can also classify Anosov Lie algebras admitting automorphisms whose polynomials p 1 have certain specified Galois groups. Theorem 1.2.  ...
