Schlichenmaier extended the theory to the multi-point situation and even to a larger class of algebras. The almost-gradedness of the algebras and the cl

Conformal and Isometric Embeddings of Gravitational Instantons,We construct isometric and conformally isometric embeddings of some gravitational instantons in . and .. In particular we show that the embedding class of the Einstein–Maxwell instanton due to Burns is equal to 3. For ., Eguchi–Hanson and anti-self-dual Taub-NUT we obtain upper and lower bounds on the embedding class.
