{\it Elements of Operatory Theory} is largely self-contained and geared
towards graduate students, mathematicians and scientists who need to
apply operator theory to their field. Written in a user- friendly,
motivating style, fundamental topics are presented systematically, i.e,
set theory, algebraic structures, topological structures, Banach spaces,
Hilbert Spaces, culminating with the Spectral Theorem. The exposition is
concept-driven and avoids the formula-computational approach. Key
features * presents required background material to each chapter *
offers 300 rigorous proofs * more than 100 examples and interesting
counterexamples * over 300 problems, many with hints. Excellent text
for the classroom and a
