Do law-invariant linear functionals collapse to the mean?

Shengzhong Chen, Niushan Gao, Denny H. Leung +1

In this note, we show that, on a wide range of rearrangement-invariant spaces, a law-invariant bounded linear functional is a scalar multiple of the expectation. We also construct…

Automatic Fatou Property of Law-invariant Risk Measures

Shengzhong Chen, Niushan Gao, Denny Leung +1

In the paper we investigate automatic Fatou property of law-invariant risk measures on a rearrangement-invariant function space $X$ other than $L^{\infty}$ . The main result…

Transformations preserving the norm of means between positive cones of general and commutative $C^{*}$ -algebras

Yunbai Dong, Lei Li, Lajos Molnar +1

In this paper, we consider a (nonlinear) transformation $Φ$ of invertible positive elements in $C^{*}$ -algebras which preserves the norm of any of the three fundamental means of posi…
