He proposed Hall's conjecture on the differences between perfect squares and perfect cubes, which remains an open problem as of 2015. Hall's work [6] on continued fractions showed that the Lagrange spectrum includes all numbers greater than 6. This interval is known as Hall's Ray. The lower limit of Hall’s ray was established by Freiman in 1975.
Roland "Ron" Edwin Larson (born October 31, 1941) is a professor of mathematics at Penn State Erie, The Behrend College, Pennsylvania. [1] He is best known for being the author of a series of widely used mathematics textbooks ranging from middle school through the second year of college.
He start[s] a school of algebra which flourished for several hundreds of years”. He also discovers the binomial theorem for integer exponents, which “was a major factor in the development of numerical analysis based on the decimal system.” c. 1000: Abū Sahl al-Qūhī (Kuhi) solves equations higher than the second degree. c. 1050
Julia Hall Bowman Robinson (December 8, 1919 – July 30, 1985) was an American mathematician noted for her contributions to the fields of computability theory and computational complexity theory—most notably in decision problems.
An analysis of early Chinese mathematics has demonstrated its unique development compared to other parts of the world, leading scholars to assume an entirely independent development. [105] The oldest extant mathematical text from China is the Zhoubi Suanjing (周髀算經), variously dated to between 1200 BC and 100 BC, though a date of about ...
John Stallings was born on July 22, 1935, in Morrilton, Arkansas. [1]Stallings received his B.Sc. from University of Arkansas in 1956 (where he was one of the first two graduates in the university's Honors program) [2] and he received a Ph.D. in Mathematics from Princeton University in 1959 under the direction of Ralph Fox.
He earned his bachelor's degree in mathematics in three years in 1938 and, a year later, a master's degree in 1939. He was awarded a Doctor of Philosophy in mathematics in 1941 [2] at the age of 22. [9] [11] [12] His doctoral advisor was Joseph L. Doob. At the time, Blackwell was the seventh African American to earn a Ph.D. in mathematics in ...
In 1949, he was invited by Weil to become professor of mathematics at the University of Chicago and accepted the position as chair of geometry. [18] [2] Coincidentally, Ernest Preston Lane, former Chair at UChicago Department of Mathematics, was the doctoral advisor of Chern's undergraduate mentor at Tsinghua—Sun Guangyuan.
