On vacuum energies and renomalizability in integrable quantum field theories
... It is known, that the above mentioned complication of mass renormalization is reconciled if one views ATFT’s in terms of dual pairs of Lie algebras. Since simply laced Lie algebras are self-dual, this picture does not ... See full document

The split property for quantum field theories in flat and curved spacetimes
... The idea that suitable inclusions of local algebras should split is due to Borchers, but the first proof of the split property (already described as “an old conjecture of Borchers”) was given in 1974 by Buchholz, in the ... See full document
