COMPUTERIZED MONITORING HAS BEEN USED for decades to study the behavior of remote users of online library resources. The older method of using transaction log analysis to study how remote users interact with online catalogs and abstracting and indexing services recently has been complemented by the use of Web server log analysis to study how remote users navigate into and through library-create...

We study (weak) log abelian varieties with constant degeneration in the log flat topology. If the base is a log point, we further study the endomorphism algebras of log abelian varieties. In particular, we prove the dual short exact sequence for isogenies, Poincaré complete reducibility theorem for log abelian varieties, and the semisimplicity of the endomorphism algebras of log abelian varieti...
