* All his life
is closely bound with the faculty of physics of St.Petersburg State University.
He studied at this faculty as a student. Afterwards he worked there at
the Department of Mathematical Physics - first as an assistant professor,
later on as an associate professor, and finally as a professor. His wife
and both his sons also have graduated from the same faculty. Over thirty
students and over fifteen postgraduate students have been his direct pupils
and around ten of them are now professors at St.Petersburg State University
and at other universities.*

* The scientific
interests of Professor V.S. Buldyrev mainly lay in the field of mathematical
theory of diffraction. His first researches were devoted to analytic study
of explicit solutions for simple models. Further he turned to asymptotic
methods. Most problems for investigation were taken by him from important
physical applications. For studies in laser physics V.S. Buldyrev was awarded
the first Leningrad university Prize. For researches in geophysics he was
awarded the State Prize. Later he established important results in the
theory of acoustic waveguides. New researches of StPetersbourg school
in diffraction theory were presented in two monographs ``Short Wave Diffraction
Theory'' and ``Spacetime Ray Method'' with coauthorship of Prof. V.S.
Buldyrev. These monographs first were published in Russia and later were
translated into English. The third book ``Mathematical Methods in Modern
Electromagnetic Diffraction Theory'' is now in press in Japan. New style
in mathematical education realized by V.S. Buldyrev at the faculty of physics
is reflected in the textbook ``Functions of Many Variables and Linear Algebra''
written by V.S. Buldyrev in collaboration with B.S. Pavlov.*

* Professor
V.S. Buldyrev leads intensive organizing activity in his scientific field.
He was the Chairman of the local organizing Committee of URSI Symposium
on Electro magnetic Theory in 1995. Many years he is a CoChairman
of the annual workshop ''Day of Diffraction''.*

* Regular participants
of the workshop ''Day of Diffraction'' and former students of Prof. V.S.
Buldyrev congratulate him with the 70th anniversary and wish him health,
energy and scientific activity. On behalf of the Organizing Committee DD99
Professor Sergey Slavyanov*
