Biography

Born in Ridderkerk, Kaashoek has studied mathematics at the Leiden University, where he received his Phd in 1964 under supervision of Adriaan Zaanen.

Kaashoek had started his academic career as assistant at the Leiden University from 1959 to 1962, and Junior Staff Member from 1962 to 1965. In 1966 he started as senior lecturer at the Vrije Universiteit, where in 1969 he was appointed professor. Among his doctoral students is Harm Bart (1973). [1] Kaashoek has been at the University of Maryland, College Park in 1975, at the University of Calgary in 1987, at the Ben-Gurion University of the Negev in 1987 and at the Tel Aviv University on various occasions. [2]

He is a member of the honorary editorial board of the Journal Integral Equations and Operator Theory, and has been appointed Knight in the Order of the Dutch Lion (Ridder in de Orde van de Nederlandse Leeuw) in 2002. In 2014 he received an honorary doctorate of North-West University in South-Africa (Potchefstroom campus). He was elected honorary member (erelid) of the Royal Dutch Mathematical Society (Koninklijk Wiskundig Genootschap) on 22 March 2016.

M. A. Kaashoek is one of the early supporters of the International Workshop on Operator Theory and its Applications (IWOTA), which was started in 1981. [3] From the beginning, M. A. Kaashoek and J. W. Helton served as vice presidents of the IWOTA Steering Committee. In addition, M. A. Kaashoek organized the third IWOTA in 1985, [4] the first time this series of conferences took place in Europe. Moreover, he maintained a website [5] documenting the complete IWOTA series.

Work

Kaashoeks research interests are in the field of 'the "analysis and Operator Theory, and various connections between Operator Theory, Matrix Theory and Mathematical Systems Theory. In particular, Wiener–Hopf integral equations and Toeplitz operators, their nonstationary variants, and other structured operators, such as continuous operator analogs of Bezout and resultant matrices. State space methods for problems in analysis. Also metric constrained interpolation problems and completion problems for partially given operators, including relaxed commutant lifting problems." [6]

In mathematics, in the area of functional analysis and operator theory, the Volterra operator, named after Vito Volterra, is a bounded linear operator on the space L2[0,1] of complex-valued square-integrable functions on the interval [0,1]. On the subspace C[0,1] of continuous functions it represents indefinite integration. It is the operator corresponding to the Volterra integral equations.
