Encyclopedia
Vera Nikolaevna Kublanovskaya (nee Totubalina; born November 21, 1920) is a Russian
mathematician
noted for her work on developing computational methods for solving spectral problems of algebra. She proposed the QR algorithm
for computing eigenvalues and eigenvectors in 1961, which has been named as one of the ten most important algorithm
s of the twentieth century. This algorithm was proposed independently by the English computer scientist John G.F. Francis
in the same year.
Kublanovskaya was born in 1920 in Krokhona, a small village near Belozersk
in Vologda Oblast
, Russia. She studied mathematics at Leningrad State University and joined the Leningrad Department of Steklov Institute of Mathematics of the USSR Academy of Sciences in 1948 where she remains to this day. In her first years at the institute from 1948 to 1955, her scientific research related to nuclear reactors under the supervision of Leonid Kantorovich
. Thereafter she defended her candidate's thesis, "The Application of Analytic Continuation in Numerical Methods of Analysis" in 1955.
In 1972, she defended her doctoral thesis, "The Use of Orthogonal Transformations in Solving Problems of Algebra."

QR algorithm
In numerical linear algebra, the QR algorithm is an eigenvalue algorithm: that is, a procedure to calculate the eigenvalues and eigenvectors of a matrix. The QR transformation was developed in the late 1950s by John G.F. Francis and by Vera N. Kublanovskaya , working independently...
