Unramified reciprocal polynomials and Coxeter decompositions
B. H. Gross Department of Mathematics, Harvard University
Abstract:
We classify certain automorphisms of an even unimodular lattice $L$ with fixed irreducible and unramified characteristic polynomial. The question which automorphisms are conjugate to their inverses in the orthogonal group of $L$ is investigated.
Key words and phrases:
Reciprocal polynomial, unimodular lattice, Coxeter decomposition, Salem number.
