In this paper we consider the class (θA, B) of parameter-dependent linear systems given by matrices A ∈ ℂn×n and B ℂn×m. This is interest for several applications frequently met task such to steer origin toward a target family f(θ) using an input that independent from parameter. provides collection necessary sufficient conditions ensemble reachability these systems.

This paper studies equilibria in second price auctions with information acquisition in an independent private value setting. We focus on the existence and uniqueness of equilibrium in the information acquisition stage for both homogenous and heterogenous bidders. It is shown that, when the relative probability gain of information acquisition is increasing, there always exists an equilibrium and...

Abstract Dysregulation of the cell cycle is an important factor in a potentially malignant oral disorder. There have not been many studies on role regulator p27 non-homogenous leukoplakia. The aim our study was to characterise protein homogenous and leukoplakias (OL), comparison with healthy mucosa squamous carcinoma tissues. current included 25 patients OL, 15 cases carcinoma, samples mucosa, ...

In this article we study Sobolev metrics of order one on diffeomorphism groups on the real line. We prove that the space Diff1(R) equipped with the homogenous Sobolev metric of order one is a flat space in the sense of Riemannian geometry, as it is isometric to an open subset of a mapping space equipped with the flat L2-metric. Here Diff1(R) denotes the extension of the group of all either comp...
