Johan Jensen was a Danish mathematician known for his work in mathematical analysis, particularly in the field of convergence and the theory of series. He was born on March 30, 1874, and passed away on June 29, 1959. One of his significant contributions is Jensen's inequality, which is a fundamental result in convex analysis. The inequality characterizes the relationship between the value of a convex function at the average of points and the average of the function values at those points.

Johannes van der Corput, also known as Jan van der Corput, was a Dutch mathematician, born on 20 November 1905 and died on 24 December 1991. He is best known for his contributions to the fields of analysis and number theory. One of his significant achievements is the development of the van der Corput method, which is a technique used in the study of exponential sums and has applications in various areas of number theory and harmonic analysis.

John Brillhart is not a widely recognized figure in popular culture or public discourse, so there may be multiple individuals with that name. If you are referring to a specific John Brillhart, such as someone notable in a certain field (like academia, arts, sciences, etc.), additional context would help clarify your inquiry.

John Pell (1611–1685) was an English mathematician known for his contributions to number theory and algebra. He is best known for Pell's equation, which is a specific type of Diophantine equation of the form \(x^2 - Dy^2 = 1\), where \(D\) is a non-square integer. Although Pell's equation had been studied before his time, Pell made significant contributions to its resolution and analysis.

John Selfridge may refer to a couple of different subjects depending on the context: 1. **John Selfridge (Retail)**: This name is commonly associated with Selfridges, a famous department store in the UK founded by Harry Gordon Selfridge in 1909. John Selfridge could be mistaken for Harry Selfridge, who was instrumental in revolutionizing the retail shopping experience.

John Wilson (born 3 October 1949) is a retired British judge who served as a High Court judge of the Queen's Bench Division in England and Wales. He was appointed to the High Court in 2011, receiving the title of Justice of the High Court. Wilson has had a distinguished career in law, having also served as a barrister before his judicial appointment.

Joseph Oesterlé is a prominent figure in both the fields of mathematics and economics, particularly known for his contributions to linear algebra and mathematical optimization.

Judy A. Holdener is a mathematician known for her work in topology and mathematical education. She has contributed to both research and teaching, focusing on areas such as algebraic topology, and has been active in promoting mathematics at various educational levels. In addition to her research, Holdener has also been involved in outreach efforts to increase the engagement and participation of underrepresented groups in mathematics.

Jurjen Ferdinand Koksma was a Dutch mathematician and philosopher, known for his work in the fields of mathematics and number theory. He was born on September 15, 1903, and passed away on March 16, 1991. Koksma contributed significantly to the study of Diophantine approximation and is recognized for Koksma's theorem, which relates to the distribution of sequences and their uniformity in different contexts.

Kohji Matsumoto could refer to a number of individuals or topics, but without specific context, it’s hard to provide an exact answer.
