TL;DR: The CM-order is a reduced order equipped with an involution that mimics complex conjugation as discussed by the authors, and the Witt-Picard group of such an order is a certain group of ideal classes.
Abstract: A CM-order is a reduced order equipped with an involution that mimics complex conjugation. The Witt--Picard group of such an order is a certain group of ideal classes that is closely related to the...

TL;DR: It is shown that if a rational map is constant on each isomorphism class of unpolarized abelian varieties of a given dimension, then it is a constant map.
Abstract: We show that if a rational map is constant on each isomorphism class of unpolarized abelian varieties of a given dimension, then it is a constant map. Our results are motivated by and shed light on a proposed construction of a cryptographic protocol for multiparty non-interactive key exchange.
