Compact Perturbations of a Multiple of the Identity

چکیده

Abstract. We give sufficient conditions on an asymptotic lp (for 1 < p < ∞) Banach space which ensure the space admits an operator which is not a compact perturbation of a multiple of the identity. These conditions imply the existence of strictly singular noncompact operators on the HI spaces constructed by G. Androulakis and the author and by I. Deliyanni and A. Manoussakis. Additionally we show that under these same conditions on the space X , l∞ embeds isomorphically into the space of bounded linear operators on X .

APPROXIMATE IDENTITY IN CLOSED CODIMENSION ONE IDEALS OF SEMIGROUP ALGEBRAS

Let S be a locally compact topological foundation semigroup with identity and Ma(S) be its semigroup algebra. In this paper, we give necessary and sufficient conditions to have abounded approximate identity in closed codimension one ideals of the semigroup algebra $M_a(S)$ of a locally compact topological foundationsemigroup with identity.

Nonlinear Dynamics and Control of Crank-Slider Mechanism with Multiple Clearance Joints

In the current study, behavior of crank-slider mechanism with single and multiple clearance joints are analyzed. Using Lankarani-Nikravesh theory for estimating discontinuous contact forces in clearance joints, relevant systems have been mathematically modeled. Through numerical simulations, perturbations in response of mechanisms with clearance joints have been analyzed. Effects of increasing ...

Culture and Identity: Linking Iranian Identity Components and Cultural Dimensions

Iranian identity cannot be conceived of as a uniform monolithic concept. But, thanks to certain upheavals in the history of the country, it has turned into the triple concept of national/Islamic/modern. Hofstede’s (2001) cultural framework represents a well-validated operationalization of culture based on six cultural dimensions  (power distance, individualism/collectivism, masculinity/feminini...

High Accuracy Relative Motion of Spacecraft Using Linearized Time-Varying J2-Perturbed Terms

This paper presents a set of linearized equations was derived for the motion, relative to an elliptical reference orbit, of an object influenced by J2 perturbation terms. Approximate solution for simulations was used to compare these equations and the linearized keplerian equations to the exact equations. The inclusion of the linearized perturbations in the derived equations increased the high ...
