MULTIPLIERS AND THEIR APPLICATIONS IN EARTHQUAKE ENGINEERING

Abstract

In this paper we shall study the multipliers on Banach algebras and We prove some results concerning Arens regularity and amenability of the Banach algebra <em>M</em>(<em>A</em>) of all multipliers on a given Banach algebra <em>A</em>. We also show that, under special hypotheses, each Jordan multiplier on a Banach algebra without order is a multiplier. Finally, we present some applications of multipliers in signal theory, and in particular in earthquake engineering.
