Abstract
We show the rigidity of a parameterized family of solvable Leibniz non-Lie algebras in arbitrary dimension, obtaining an irreducible component in the variety that does not intersect the variety of Lie algebras non-trivially. Moreover it is shown that for any
the Abelian Lie algebra
appears as the algebra of derivations of a solvable Leibniz algebra.
