Carol Lee Walker (born 1935) is a retired American mathematician and mathematics textbook author. Walker's early mathematical research, in the 1960s and 1970s, concerned the theory of abelian groups. In the 1990s, her interests shifted to fuzzy logic and fuzzy control systems. ^[1]

Education and career

Walker was born in Martinez, California on August 19, 1935, and went to high school in Montrose, Colorado. She studied music education at the University of Colorado Boulder, with a year off to work as a primary-school music teacher in Colorado, and graduated in 1957. Next, she went to the University of Denver for graduate study in mathematics, but after one year transferred to New Mexico State University, ^[2] where she earned a master's degree in 1961 and completed her PhD in 1963. ^[1] Her dissertation, On ${\displaystyle p^{\alpha }}$-pure sequences of abelian groups, was supervised by David Kent Harrison. ^{[2] [3]}

After postdoctoral research at the Institute for Advanced Study, she returned to Mexico State University as an assistant professor in 1964, and quickly earned tenure as an associate professor in 1966. She was promoted to full professor in 1972. She chaired the Department of Mathematical Sciences from 1979 to 1993, and served as associate dean of arts and sciences from 1993 until her retirement in 1996. ^[1]

Personal life

Walker was married to Elbert Walker (1930–2018), another mathematician who joined the New Mexico State University faculty in 1957. ^[8]
