Universal functions on nonsimply connected domains

Antonios D. Melas (2001)

Annales de l’institut Fourier

Similarity:

We establish certain properties for the class 𝒰 ( Ω , ζ 0 ) of universal functions in Ω with respect to the center ζ 0 Ω , for certain types of connected non-simply connected domains Ω . In the case where / Ω is discrete we prove that this class is G δ -dense in H ( Ω ) , depends on the center ζ 0 and that the analog of Kahane’s conjecture does not hold.

Commutators associated to a subfactor and its relative commutants

Hsiang-Ping Huang (2002)

Annales de l’institut Fourier

Similarity:

Let N M be an inclusion of I I 1 factors with finite Jones index. Then M = ( N ' M ) [ N , M ] as a vector space. Here [ N , M ] denotes the vector space spanned by the commutators of the form [ a , b ] where a N , b M .
