Cohomologically Rigid Solvable Leibniz Algebras with Nilradical of Arbitrary Characteristic Sequence


We describe the (n + s)-dimensional solvable Leibniz algebras whose nilradical has characteristic sequence (m1, …, ms), where m1 +⋯+ ms = n. The completeness and cohomological rigidity of this algebra are proved.
