## Linear analysis. An introductory course.(English)Zbl 0753.46002

Cambridge Mathematical Textbooks. Cambridge etc.: Cambridge University Press,. xi, 240 p. (1990).
This book is an introduction to linear functional analysis. The exposition is clear, enthusiastic, precise, with scientific rigor and many exercises. So it may be strongly recommended as a basic textbook.
Together with classical materials such as the Hahn-Banach theorem, Baire theorem, contractions, duality, Hilbert spaces, or algebras of operators; it also includes special topics such as the geometry of finite dimensional spaces and fixed point theorems. On the other hand, notes at the end of the chapters briefly describe the origin and evolution of the subjects from the bibliographic point of view. So the present book may be also recommended to postgraduated students or for consultation.
