The answer is quite similar to the Theorem of Duistermaat and Singer for the usual alge- bra of pseudo-differential operators where all automorphisms are given by conjugation by

In the Arctic tundra, snow is believed to protect lemmings from mammalian predators during winter. We hypothesised that 1) snow quality (depth and hardness)

Arguments of Demailly [De] Lemma 3.7, can then be used to prove the positivity of this Hermitian line bundle when (£',[| ||^) is positive, and the trick of Getzler [Ge] together

Kadison-Singer had shown that pure states on continuous maximal abelian subalgebras (masas) of B(H) do not extend uniquely to pure states on the full algebra and conjectured the

Cette conjecture est vraie dans de nombreux cas, en particulier pour l’espace de Hardy H 2 ; voir [10] pour plus de détails.. Par ailleurs, il est observé dans [19] que toute suite
