Nina Nikolaevna Uraltseva is a renowned Professor of Mathematics and head of the Section of Mathematical Physics and Partial Differential Equations at Saint Petersburg State University. She has been a leading figure in the study of nonlinear partial differential equations, particularly focusing on elliptic and parabolic PDEs. Her work has significantly influenced the field, with foundational contributions to regularity theory and free boundary problems. Education: Born in 1935 in Leningrad, she graduated from Leningrad State University in 1956 with a physics degree. She earned her Ph.D. in 1960 and a second doctoral science degree in 1964, both under Olga Ladyzhenskaya. She became a full professor in 1966 and has led her department since 1977. Research Interests: Uraltseva's research centers on nonlinear PDEs, including elliptic and parabolic equations, free boundary problems, and variational inequalities. Her collaborations with Ladyzhenskaya produced seminal works like Linear and Quasilinear Equations of Elliptic Type (1964) and Linear and Quasi-linear Equations of Parabolic Type (1968). These texts remain foundational in PDE theory. Awards and Honors: She has received the Chebyshev Prize (USSR Academy of Sciences), State Prize (USSR), Humboldt Research Award (2006), and an Honorary Doctorship from KTH (2006). In 2005, she delivered the European Mathematical Society's annual lecture. Contributions: Uraltseva has authored over 150 research articles and books, advised numerous doctoral students, and played a pivotal role in advancing the field through editorial and leadership roles. Her work on free boundary problems, including obstacle-type equations and two-phase membrane problems, has been widely recognized.
