《應用泛函分析(第2捲)(英文版)》內容簡介：More precisely, by （i）, I mean a systematic presentation of the materialgoverned by the desire for mathematical perfection and completeness ofthe results. In contrast to （i）, approach （ii） starts out from the question"What are the most important applications？" and then tries to answer thisquestion as quickly as possible. Here, one walks directly on the main roadand does not wander into all the nice and interesting side roads.

The present book is based on the second approach. It is addressed toundergraduate and beginning graduate students of mathematics, physics,and engineering who want to learn how functional analysis elegantly solvesma~hematical problems that are related to our real world azld that haveplayed an important role in the history of mathematics. The reader shouldsense that the theory is being developed, not simply for its own sake, butfor the effective solution of concrete problems.
