American mathematician
Howard Garland (born 27 October 1937, in Detroit )[ 1] is an American mathematician, who works on algebraic groups , Lie algebras (structure theory and representation theory ), and infinite-dimensional algebras.[ 2]
Garland received in 1958 his bachelor's degree from the University of Chicago , in 1959 his master's degree from Wayne State University , and in 1964 his Ph.D. from the University of California, Berkeley under S. S. Chern with thesis On the cohomology of lattices in Lie groups ).[ 3] As a postdoc he was in 1964–1965 an instructor at Yale University and in 1965–1966 a visiting scholar at the Institute for Advanced Study .[ 4] At Yale University he became in 1966 an assistant professor, in 1969 an associate professor, and in 1973 a full professor. Garland was a visiting professor in 1969–1970 at Columbia University and in 1972–1973 at the State University of New York at Stony Brook .
In 1986 Garland, with his doctoral student Igor Frenkel and with Gregg Zuckerman , applied Feigin 's theory of semi-infinite cohomology of graded Lie algebras to explain some aspects of the BRST quantization of string theory.[ 5]
