جبرهای توپولوژیکی

This text, devoted to general topological algebras, presents a self-contained and systematic exposition of basic topics concerning such algebras. Both complex and real topological algebras, with and without unity, have been treated. A basic background in algebra, functional analysis and general topology, is required to understand this book. 1.1.1. Recall that in a ring R an element el (respy. + er) is called a left (respy. right) unity if ela = a (respy. aer = a) for all a in R.
