Some irreducible components of the variety of complex $n+1$-dimensional Leibniz algebras

In the present paper we indicate some Leibniz algebras whose closures of orbits under the natural action of ${\text{GL}}_n$ form an irreducible component of the variety of complex $n$-dimensional Leibniz algebras. Moreover, for these algebras we calculate the bases of their second groups of cohomologies.
