He was the author of the textbook "Mathematical Analysis"[1] for students of mathematical and physical specialties of higher education, which was reprinted several times and translated into many languages.

Zorich was an expert in various fields of mathematical analysis, conformal geometry, and the theory of quasi-conformal mappings.

He graduated from the Faculty of Mechanics and Mathematics at the Moscow State University in 1960.

In 1963 he graduated from the faculty's graduate school (Department of Theory of Functions and Functional Analysis) and defended his thesis "Compliance boundaries for some classes of mappings in space", which was noted as outstanding.

In 1969 he defended his doctoral thesis "Global reversibility of quasi-conformal mappings of space".
