Biography: 

V.A.Yurko was born on 28 August 1949 in Ozinki, Saratov district, Russia. In 1971 he received 

his University Diploma in mathematics from Saratov State University (Department of Mathematics

and Mechanics). In 1971-1974 he was a post-graduate student of the same department. In 1975 

V.A. Yurko received the Kandidat of Sciences  degree (Ph.D.) from  Saratov State University.

He was an assistant professor of mathematics in Saratov Polytechnical Institute (1974-1977) 

and an associate professor (docent) of the Department of Mathematics and Mechanics in Saratov

State University (1977-1991). In 1992 he received the Doctor of Siences degree from Moscow State

University. Since 1991 he is a full professor of mathematics of the Department of Mathematics and

Mechanics in Saratov State University, and the Head of the Chair of Mathematical Physics and 

Numerical Analysis.

 

Research  interests of Prof. Yurko include spectral theory, theory of differential and integral 

equations, mathematical physics, inverse problems, numerical analysis. The first thesis of 

V.A. Yurko (for the Kandidat of Science degree (PhD), 1975) was devoted to uniqueness theorems 

of recovering parameters of differential operators with desirable spectral properties. The method

developed in this work made it possible to describe the uniqueness classes for arbitrary order 

differential operators on a finite interval.

 

The second thesis of V.A. Yurko (for the Doctor of Science degree, 1992) titled "Inverse Problems 

for Differential Operators" was defended in Moscow State University. Inverse problems of spectral 

analysis which consist in recovering operators from their spectral characteristics are of high

interest to many researchers due to the fundamental role that inverse problems play in various 

areas of mathematics, natural sciences, and engineering. At the same time the nonlinearity of many

important classes of inverse problems makes them an extremely difficult area of research. That is 

why by the end of the 1980s more or less complete results have been received only for Sturm-Liouville

and Dirac differential operators. In a major part of his works, Prof. Yurko has constructed the 

inverse problem theory for arbitrary order differential operators and systems for regular and 

singular cases. He has developed a new approach that allowed him to give the complete solution of 

these classes of inverse spectral problems, obtain necessary and sufficient conditions for their 

solvability, create numerical algorithms, and study stability properties of the solutions. Nowadays

his main method (called the method of spectral mappings) is the most universal tool for studying 

invrse spectral problems for various classes of operators.

 

The important part of Prof. Yurko's works is devoted to the so-called incomplete inverse problems 

that arise when only a part of spectral information is available. He has suggested a new method 

(called the method of standard models) for constructing solutions of a wide class of incomplete

inverse problems, gave their classification, and described the degenerate cases. For differential

operators on the half-line the most difficult case for research is when the coefficients of the 

differential equation grow at infinity. In part of his works devoted to these classes of operators,

V.A. Yurko introduced a new class of spectral characteristics in a special space of distributions 

and gave the solution of the inverse problem for higher-order differential operators on the 

half-line with locally integrable coefficients.

 

A number of important Yurko's works are devoted to boundary value problems on spatial networks 

(geometrical graphs). Such problems often appear in natural sciences and engineering. In this part

of works Prof. Yurko created a general theory for constracting solutions of nonlinear inverse

problems for arbitrary spatial networks.

 

V.A. Yurko has also produced important results in the theory of boundary value problems for 

differential equations with singularities and turning points, in the theory of non-local inverse 

problems, in the theory of the so-called discontinuous boundary value problems and other major 

areas of the theory of differential and integral equations and spectral theory.

 

An important part of Prof. Yurko s' works is devoted to the applications of spectral theory in 

natural sciences and engineering.  In particular, he has publications in elasticity theory, solid

mechanics, electronics, astrophysics, and theory of nonlinear waves.

 

In total V.A. Yurko has published more than 500 research articles and 10 monographs. He has 

received over 60 research grants from various international and Russian funds.
