On Bol algebras that satisfies some supplementary conditions. In the paper Bol
algebras are approached through
Lie algebras On Laplace invariants for equations with dominating third-order partial derivative and two independent variables are written in terms of them. Classes of equations which admit four-dimensional
Lie algebras are distinguished.
Almost Inner Derivations of Some Leibniz Algebras.
Namely, we consider a thin
