Every finitely generated group is weakly exact
Ronald G. Douglas, Piotr W. Nowak
We show that every finitely generated group admits weak analogues of an invariant expectation, whose existence characterizes exact groups. This fact has a number of applications. W…
Some properties of the moment estimator of shape parameter for the gamma distribution
Piotr Nowak
Exact distribution of the moment estimator of shape parameter for the gamma distribution for small samples is derived. Order preserving properties of this estimator are presented.
Order preserving property of moment estimators
Piotr Nowak
Balakrishnan and Mi [1] considered order preserving property of maximum likelihood estimators. In this paper there are given conditions under which the moment estimators have the p…
A note on stochastic ordering of estimators of exponential reliability
Piotr Nowak
Recently Balakrishnan and Iliopoulos [Ann. Inst. Statist. Math. 61 (2009)] gave sufficient conditions under which maximum likelihood estimator (MLE) is stochastically increasing. I…
Poincaré inequalities and rigidity for actions on Banach spaces
Piotr W. Nowak
The aim of this paper is to extend the framework of the spectral method for proving property (T) to the class of reflexive Banach spaces and present a condition implying that every…
Residually finite actions and crossed products
David Kerr, Piotr W. Nowak
We study a notion of residual finiteness for continuous actions of discrete groups on compact Hausdorff spaces and how it relates to the existence of norm microstates for the reduc…
