Adi Ben-Israel

Adi Ben-Israel (born November 6, 1933) is a mathematician and an engineer, working in applied mathematics, optimization, statistics, operations research and other areas.

Ben-Israel's research has included generalized inverses of matrices, in particular the Moore–Penrose pseudoinverse,[2] and of operators, their extremal properties, computation and applications.

In the area of linear algebra, he studied the matrix volume[3] and its applications, basic, approximate and least-norm solutions,[4] and the geometry of subspaces.

Ben-Israel's research into optimization included linear programming, a Newtonian bracketing method of convex minimization, input optimization, and risk modeling of dynamic programming, and the calculus of variations.

He also studied various aspects of clustering and location theory, and investigated decisions under uncertainty.
