real analysis
In mathematics, the branch of real analysis studies the behavior of real numbers, sequences and series of real numbers, and real functions. Some particular properties of real-valued sequences and functions that real analysis studies include conv ...
and
functional analysis
Functional analysis is a branch of mathematical analysis, the core of which is formed by the study of vector spaces endowed with some kind of limit-related structure (e.g. inner product, norm, topology, etc.) and the linear functions defined o ...
. Fichtenholz was one of the founders of the Leningrad school of real analysis.
He also authored a three-volume textbook 'Differential and Integral Calculus'. The books cover mathematical analysis of function of one real variable, functions of many real variables and of complex functions. Due to depth and precision of presentation of material, these books are defined as classical position in mathematical analysis. Book was translated, among others, into German, Polish, Chinese, Vietnamese, and Persian however translation to English language has not been done still.
Fichtenholz's books about analysis are widely used in Middle and Eastern European as well as Chinese universities due to its exceptionality of detailed and well-ordered presentation of material about mathematical analysis. Due to unknown reasons, these books do not have the same fame in universities in other areas of the world.
He was an Invited Speaker of the
ICM in 1924 in Toronto.
