We construct a bialgebra object in the category of linear maps LMfrom a cocommutative rack bialgebra. Theconstruction does extend to somenon-cocommutative rack bialgberas, as isillustrated by a concrete example. As a separate result, we show that the Loday complex with adjoint coefficients embeds into the rack bialgebra deformation complex for the rack bialgebra defined by a Leibniz algebra. 查看全文>>
