Malcev dialgebras

We apply Kolesnikov’s algorithm to obtain a variety of nonassociative algebras defined by right anticommutativity and a `noncommutative’ version of the Malcev identity. We use computational linear algebra to verify that these identities are equivalent to the identities of degree <= 4 satisfied by the dicommutator in every alternative dialgebra. We extend these computations to show that any special identity for Malcev dialgebras must have degree at least 7. Finally, we introduce a trilinear operation which makes any Malcev dialgebra into a Leibniz triple system.
