The sirens’ call in psychometrics: The invariance of IRT models
(Sage, 2017-06)
The idea that item response theory (IRT) models yield invariant parameter estimates is widely accepted among scholars interested in achieving truly scientific measurements in social and behavioral sciences. Starting from ...
Convergence to the maximal invariant measure for a zero-range process with random rates

An approximation problem in multiplicatively invariant spaces
(American Mathematical Society, 2017-07)
Let H be Hilbert space and (Ω, m) a σ-finite measure space. Multiplicatively invariant(MI) spaces are closed subspaces of L2(Ω, H) that are invariant under point-wise multiplication byfunctions from a fixed subset of L∞(Ω). ...
Countable contraction mappings in metric spaces: Invariant Sets and Measures
(Versita, 2014-04)
We consider a complete metric space (X, d) and a countable number of contraction mappings on X, F = {Fi : i ∈ N}. We show the existence of a smallest invariant set (with respect to inclusion) for F. If the maps Fi are of ...

Invariance of 0-currents under diffusions
(World Scientific Publ Co Pte Ltd, 2017-04-01)
We study two actions of a stochastic flow psi(t) on the space of 0-currents T of a differentiable manifold M. In particular, we give conditions on a current T to be invariant under these actions. Also, we apply our results ...
