Classification of four-dimensional anti-dendriform algebras whose associated associative algebra has a one-dimensional annihilator

Source abstract

This paper is devoted to the classification of four-dimensional anti-dendriform algebras over the field of complex numbers. Such algebras are defined by the presence of two binary operations whose sum determines an associative multiplication. The algebra obtained with respect to this multiplication is called the associated associative algebra, which is necessarily nilpotent. In the present paper, we obtain a classification of all four-dimensional anti-dendriform algebras associated with four-dimensional associative algebras whose annihilator is one-dimensional.
