Varieties of nilpotent Jordan superalgebras of dimension five

Isabel HernÃ¡ndez, Laiz Valim da Rocha, Rodrigo Lucas Rodrigues

The paper is devoted to the description of the varieties of complex 5-dimensional nilpotent Jordan superalgebras. We find all representatives for the isomorphism classes, using the…

Classification of almost abelian Lie groups admitting left-invariant complex or symplectic structures

Romina M. Arroyo, MarÃa L. Barberis, VerÃ³nica S. Diaz +2

We classify the almost abelian Lie algebras $g_{A} = R e_{0} ⋉_{A} R^{2 n - 1}$ admitting complex or symplectic structures. The matrix $A\in M(2n-1,\mathbb R )…

Irreducible Components of the Varieties of Jordan Superalgebras of Types $(1, 3)$ and $(3, 1)$

Isabel HernÃ¡ndez, MarÃa Eugenia Martin, Rodrigo Lucas Rodrigues

We describe the variety of Jordan superalgebras of dimension $4$ whose even part is a Jordan algebra of dimension $1$ or $3$ . We prove that the variety is the union of Zariski clos…
