Nonstandard Analysis is an enlargement of Standard (or Ordinary) Mathematics. It gives a strictly logical foundation of Leibnitz's infinitesimals. It enables to understand better and simplify a lot of Standard Mathematics. Besides it advances new mathematical problems. The intersection of this work with other textbooks in Nonstandard Analysis is minimal. A principal accent of the theory of linear operators is taken. Mathematical Studies: Monograph Series. Volume 3
