Barbara Lee Keyfitz works in mathematical analysis of partial differential equations, focusing on conservation laws and gas dynamics—mathematical models used to describe how quantities like mass, momentum, and energy move and change in fluids and gases over time. Her recent work looks at how solutions to these equations behave under small changes in starting conditions, including special cases like shock waves and singular solutions, with applications relevant to fluid and gas flow. This is theoretical mathematics research aimed at understanding the stability and well-posedness of such models.
Publication output over the last decade has been modest and irregular, with occasional gaps (e.g., 2019-2020, 2025) interspersed with small clusters of one to two papers per year.
