RT Dissertation/Thesis T1 Braided Crossed Modules and Loday-Pirashvili category A1 Fernández Fariña, Alejandro K1 Braided category K1 Crossed Module K1 Lie Algebra K1 Leibniz Algebra K1 universal central extension K1 Loday-Pirashvili category AB This thesis is devoted to the study of braidings in different mathematicalcontexts, as well as in a deeper analysis of the Loday-Pirashvili category.We will study the notion of braidings for crossed modules and internal categories in the cases of groups,associative algebras, Lie algebras and Leibniz algebras, showing the equivalence between the respectivecategories.We will also study universal central extensions in the category of braided crossed modules of Lie algebras.Finally, we will show how to generalize the Loday-Pirashvili category. With that construction, we will exhibit ageneralization of the relationship between Lie and Leibniz objects.
