Weil Representation of a Generalized Linear Group over a Ring of Truncated Polynomials over a Finite Field Endowed with a Second Class Involution
We construct a complex linear Weil representation of the generalized
special linear group (,
the quadratic extension of the finite field of elements, odd),
where is endowed with a second class involution. After the construction
of a specific data, the representation is defined on the generators of a Bruhat
presentation of , via linear operators satisfying the relations of the
presentation. The structure of a unitary group associated to is
described. Using this group we obtain a first decomposition of

Free 2-step nilpotent Lie algebras and indecomposable representations
Given an algebraically closed field F of characteristic 0 and an F-vector space V, let L(V) = V⊕Λ2(V) denote the free 2-step nilpotent Lie algebra associated to V. In this paper, we classify all uniserial representations of the solvable Lie algebra &= ⟨x⟩⋉L(V), where x acts on V via an arbitrary invertible Jordan block.Fil: Cagliero, Leandro Roberto.
