Solitons and nonsmooth diffeomorphisms in conformal nets
Simone Del Vecchio, Stefano Iovieno, Yoh Tanimoto
We show that any solitonic representation of a conformal (diffeomorphism covariant) net on S^1 has positive energy and construct an uncountable family of mutually inequivalent soli…

Positive energy representations of Sobolev diffeomorphism groups of the circle
Sebastiano Carpi, Simone Del Vecchio, Stefano Iovieno +1
We show that any positive energy projective unitary representation of Diff(S^1) extends to a strongly continuous projective unitary representation of the fractional Sobolev diffeom…
