Abstract: Corings (also known as bocses) are generalisations of coalgebras. Corings can be constructed from certain embeddings of algebras. Conversely, there are algebras associated with corings. This allows to translate structure and properties from corings to algebras and vice versa. This will be illustrated in the context of quasi-hereditary algebras and exact Borel subalgebras.
