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 19711974
he was a postgraduate 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 (19741977) and an associate professor (docent)
of the Department of Mathematics and Mechanics in Saratov State University
(19771991). In 1992 he received the Doctor of Siences degree from Moscow
State University. Since 1991 he is a 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 & integral equations, mathematical physics, inverse problems.
The first thesis of V.A. Yurko (for the Kandidat of Science degree, 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 SturmLiouville 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.
The important part of Prof. Yurko s' works is devoted to the socalled
incomplete inverse problems that arise when only a part of spectral
information is available. He has suggested a new method for constructing
solutions of a wide class of incomplete inverse problems, gave their
classification, and described the degenerate cases.
For differential operators on the halfline 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
higherorder differential operators on the halfline with locally
integrable coefficients.
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 nonlocal inverse problems, in the theory of the
socalled discontinuous boundary value problems, spectral theory of
differential operators on spatial networks 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 300 research articles and
7 monographs. He has received over 40 research grants from international
and Russian funds including grants from Russian Foundation for Basic
Research, grants from Russian Ministry of Education, Volkswagen Foundation
Grant, Leonard Euler Grants; grants from ISF, DAAD, DFG, Tubitak, ISAAC,
NSC, QNRF and other research funds. Prof. Yurko is a Fellow of Russian
Academy of Natural Sciences and American Mathematical Society.
