Sun - Yung Alice Chang ( born March 24, 1948 in Xi'an, China ) is a Chinese -born American mathematician who deals with analysis.

It is SY Chang, SYA Chang and A. Chang quoted.

Chang moved shortly after the takeover by the Communists in China (1949 ) to Taiwan with her family, graduated from the National Taiwan University ( Bachelor's degree 1970) and received his doctorate in 1974 at the University of California, Berkeley with Donald Sarason ( On the structure of some Douglas Subalgebras ). After that, she was 1974/75 Assistant Professor at the State University of New York at Buffalo, then to 1977 assistant professor at UCLA and from 1977 to 1980 at the University of Maryland at College Park. From 1980, she was Associate Professor and from 1982 professor at UCLA. She stayed there, only interrupted by a 1989 as a professor at the University of California, Berkeley until 2000. Additionally, she was from 1998 professor at Princeton University, where she was from 2002 to 2006 Director of the Graduate Center of the mathematical faculty. She was a visiting scholar at the Institute for Advanced Study (1976 /77) and the ETH Zurich.

Chang dealt among other things with the boundary behavior bounded analytic functions on the unit disk, real harmonic analysis and applications of partial differential equations in geometric problems, such as the study of the spectrum of the Laplace operator on manifolds, the study of partial differential equations for the Gaussian curvature on the sphere and the conformal geometry of four-dimensional manifolds.

Chang was 1979/80 Sloan Fellow and Guggenheim Fellow in 1999. In 1986 she was invited speaker at the ICM, Berkeley ( Extremal functions in a sharp form of Sobolev inequality ) and in 2002 she held on the ICM in Beijing a plenary lecture with her husband, Paul C. Yang ( Nonlinear partial differential equations in conformal geometry ). 1989 to 1991 she was Vice President of the American Mathematical Society. In 1995 she received the Ruth Lyttle Satter Prize of the AMS and 2001 she was a Noether Lecturer. In 2009 she became a member of the National Academy of Sciences.

She is married to the mathematician Paul C. Yang, who is also a professor at Princeton and with whom she also collaborated, and has a daughter and a son.
