Von Neumann's inequality In operator theory, von Neumann's inequality, due to John von Neumann, states that, for a fixed contraction "T", the polynomial functional calculus map is itself a contraction.

John von Neumann John von Neumann ( ; Hungarian: "Neumann János Lajos" , ] ; December 28, 1903 – February 8, 1957) was a Hungarian-American mathematician, physicist, and computer scientist. He made major contributions to a number of fields, including mathematics (foundations of mathematics, functional analysis, ergodic theory, representation theory, operator algebras, geometry, topology, and numerical analysis), physics (quantum mechanics, hydrodynamics, and quantum statistical mechanics), economics (game theory), computing (Von Neumann architecture, linear programming, self-replicating machines, stochastic computing), and statistics.

Vilfredo Pareto Vilfredo Federico Damaso Pareto (] ; born Wilfried Fritz Pareto, 15 July 1848 – 19 August 1923) was an Italian engineer, sociologist, economist, political scientist, and philosopher, now also known for the 80/20 rule, named after him as the Pareto principle. He made several important contributions to economics, particularly in the study of income distribution and in the analysis of individuals' choices. He was also responsible for popularising the use of the term "elite" in social analysis.

David Hilbert David Hilbert (] ; 23 January 1862 – 14 February 1943) was a German mathematician. He is recognized as one of the most influential and universal mathematicians of the 19th and early 20th centuries. Hilbert discovered and developed a broad range of fundamental ideas in many areas, including invariant theory and the axiomatization of geometry. He also formulated the theory of Hilbert spaces, one of the foundations of functional analysis.

Paul Samuelson Paul Anthony Samuelson (May 15, 1915 – December 13, 2009) was an American economist and the first American to win the Nobel Memorial Prize in Economic Sciences. The Swedish Royal Academies stated, when awarding the prize in 1970, that he "has done more than any other contemporary economist to raise the level of scientific analysis in economic theory". Economic historian Randall E. Parker calls him the "Father of Modern Economics", and "The New York Times" considered him to be the "foremost academic economist of the 20th century".

Herman Otto Hartley H. O. Hartley (1912 – 1980), born Herman Otto Hirschfeld but commonly called HOH, was a German-American statistician. He developed Hartley's test for equality of variances (published in 1950). In 1953 he was elected as a Fellow of the American Statistical Association. In 1967 he and J.N.K. Rao published a maximum likelihood method for finding variance components in mixed models. He made significant contributions in mathematical programming, optimization, and survey sampling.

Pierre de Fermat Pierre de Fermat (] ; (Between 31 October and 6 December 1607 – 12 January 1665) was a French lawyer at the "Parlement" of Toulouse, France, and a mathematician who is given credit for early developments that led to infinitesimal calculus, including his technique of adequality. In particular, he is recognized for his discovery of an original method of finding the greatest and the smallest ordinates of curved lines, which is analogous to that of differential calculus, then unknown, and his research into number theory. He made notable contributions to analytic geometry, probability, and optics. He is best known for his Fermat's principle for light propagation and his Fermat's Last Theorem in number theory, which he described in a note at the margin of a copy of Diophantus' "Arithmetica".

Alexander Aitken Alexander Craig "Alec" Aitken (1 April 1895 – 3 November 1967) was one of New Zealand's greatest mathematicians. In a 1935 paper he introduced the concept of generalized least squares, along with now standard vector/matrix notation for the linear regression model. Another influential paper co-authored with his student Harold Silverstone established the lower bound on the variance of an estimator, now known as Cramér–Rao bound.
