  • Summary

    Any deterministic process loses information, and one can quantify the amount of information lost. Information loss is a generalization of entropy, and in some ways is a better-behaved quantity, being more functorial. We give a simple axiomatic characterization of information loss.

  • In this paper, we present a conjecture on a relation between the Zelevinski involutions for reductive groups over a p-adic field and the conjectural A-packets. As evidence for this conjecture, we prove that the Zelevinski involutions, which are regarded as operators on the space of virtual characters, commute with the endoscopic transfers under the assumption of the fundamental lemma for groups and for Lie algebras.
