Abstract

In this paper we explore relationship between representations of a Jordan algebra \J\J and the Lie algebra \g\g obtained from \J\J by the Tits-Kantor-Koecher construction. More precisely, we construct two adjoint functors Lie:\JJ\ggmLie :\JJ\to \ggm and Jor:\ggm\JJJor:\ggm\to\JJ, where \JJ\JJ is the category of unital \J\J-bimodules and \ggm\ggm is the category of \g\g-modules admitting a short grading. Using these functors we classify \J\J such that its semisimple part is of Clifford type and the category \JJ\JJ is tame.
