Griffith Baley Price
G. Baley Price (14 March 1905, Brookhaven, Mississippi – 7 November 2006, Lawrence, Kansas) was an American mathematician and historian of American mathematics. He was a president of the Mathematical Association of America. Career. After graduating with an A.B. from Mississippi College in 1925, G. B. Price went to Harvard University, where he received his M.A. in 1928 and his Ph.D. in 1932 under G. D. Birkhoff with thesis "Double Pendulum and Similar Dynamical Systems". Apart from a period of service with the U.S. Army Air Force in England in World War II, Price was a mathematics professor  at the University of Kansas from 1937 to 1975 and chair of the mathematics department from 1951 to 1970. He was the co-author of two textbooks (published in 1966 and 1968) and the author of a history of the department of mathematics of the University of Kansas and several articles related to the role of mathematics and mathematicians in World War II. He was president of the Mathematical Association of America (MAA) for the two years 1957–1958 and received the MAA's distinguished service award in 1970. Price based his book about multicomplex spaces and functions on Corrado Segre 's work where formula_1 has n imaginary units formula_2 all of which commute. But the book primarily treats bicomplex numbers formula_3 Since formula_4 the numbers formula_5 and formula_6 are idempotent. The idempotents provide an alternate basis for the bicomplexes: Differentiable bicomplex functions f are shown to correspond to a pair of differentiable complex functions f and f:
