Harm Bart (born 5 August 1942) is a Dutch mathematician, economist, and Professor of Mathematics at the Erasmus University Rotterdam,particularly known for his work on "factorization problems for matrix and operator functions."
A mathematician is someone who uses an extensive knowledge of mathematics in his or her work, typically to solve mathematical problems.
An economist is a practitioner in the social science discipline of economics.
Erasmus University Rotterdam is a public university located in Rotterdam, Netherlands. The university is named after Desiderius Erasmus Roterodamus, a 15th-century humanist and theologian.
Born in Enkhuizen, Bart started his study at the Vrije Universiteit in Amsterdam in 1960. Here he received his BA in Mathematics and Astronomy in 1964, his MA in Mathematics with a minor in Dogmatics in 1969, and his PhD in 1973 with the thesis "Meromorphic operator valued functions" under supervision of Rien Kaashoek.
Astronomy is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets; the phenomena also includes supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, all phenomena that originate outside Earth's atmosphere are within the purview of astronomy. A related but distinct subject is physical cosmology, which is the study of the Universe as a whole.
Marinus Adriaan (Rien) Kaashoek is a Dutch mathematician, and Emeritus Professor Analysis and Operator Theory at the Vrije Universiteit in Amsterdam.
After graduation Bart started his academic career at the Faculty of Mathematics at the Vrije Universiteit as Assistant Professor in 1973, and Associate Professor at the Faculty of Mathematics and Computer Science in 1977. In 1982 he was appointed Professor at the Faculty of Mathematics and Computer Science of the Eindhoven University of Technology. In 1984 he became Extraordinary Professor of Mathematics and since 1985 Professor of Mathematics at the Erasmus School of Economics of the Erasmus University Rotterdam. Among his doctoral students are Stephanus van Eijndhoven (1983) and Robertus Zuidwijk (1994).From 1987 to 1992 he was Co-Director of the Econometric Institute, first with Teun Kloek and later with Ton Vorst. From 1996 to 2000 he was also Dean of the Erasmus School of Economics.
The Eindhoven University of Technology, abbr. TU/e, is a technical university in the Netherlands, operating in English. It is a leading European university in engineering and technology and a world's top university in terms of research cooperation with industry.
Econometric Institute at the Erasmus University Rotterdam is a leading research institute in the fields of econometrics and management science in the Netherlands. The Institute offers advanced education in econometrics. It was founded in 1956 by Henri Theil in cooperation with Jan Tinbergen.
Teunis (Teun) Kloek is a Dutch economist and Emeritus Professor of Econometrics at the Erasmus Universiteit Rotterdam. His research interests centered on econometric methods and their applications, especially nonparametric and robust methods in econometrics.
In 2004 Bart was decorated as Officer in the Order of Orange-Nassau.He has been elected Fellow of the Stieltjes Institute for Mathematics, and Fellow of the Tinbergen Institute.
The Order of Orange-Nassau is a civil and military Dutch order of chivalry founded on 4 April 1892 by the Queen regent Emma, acting on behalf of her under-age daughter Queen Wilhelmina.
The Tinbergen Institute is a joint institute for research and education in economics, econometrics and finance of the University of Amsterdam, the VU University Amsterdam and the Erasmus University Rotterdam. The institute was founded in 1987 and is named after the Dutch economist Jan Tinbergen, a Nobel prize-winning professor at the Erasmus University Rotterdam.
Bart authored and co-authored three books and over fifty articles.
Israel Gohberg was a Bessarabian-born Soviet and Israeli mathematician, most known for his work in operator theory and functional analysis, in particular linear operators and integral equations.

Calyampudi Radhakrishna Rao, FRS known as C R Rao is an Indian-American mathematician and statistician. He is currently professor emeritus at Pennsylvania State University and Research Professor at the University at Buffalo. Rao has been honoured by numerous colloquia, honorary degrees, and festschrifts and was awarded the US National Medal of Science in 2002. The American Statistical Association has described him as "a living legend whose work has influenced not just statistics, but has had far reaching implications for fields as varied as economics, genetics, anthropology, geology, national planning, demography, biometry, and medicine." The Times of India listed Rao as one of the top 10 Indian scientists of all time. Rao is also a Senior Policy and Statistics advisor for the Indian Heart Association non-profit focused on raising South Asian cardiovascular disease awareness.

Henri (Hans) Theil was a Dutch econometrician, Professor at the Netherlands School of Economics in Rotterdam, known for his contributions to the field of econometrics.
Numerical linear algebra is the study of how matrix operations can be used to create computer algorithms which efficiently and accurately provide approximate answers to mathematical questions. It is a subfield of numerical analysis, and a type of linear algebra. Because computers use floating-point arithmetic, they cannot exactly represent irrational data, and many algorithms increase that imprecision when implemented by a computer. Numerical linear algebra uses properties of vectors and matrices to develop computer algorithms that minimize computer error while retaining efficiency and precision.
