Tatyana Olegovna Shaposhnikova (Russian: Татьяна Олеговна Шапошникова, born 1946)[1] is a Russian-born Swedish mathematician.
She is best known for her work in the theory of multipliers in function spaces, partial differential operators and history of mathematics, some of which was partly done jointly with Vladimir Maz'ya.
[6] In March 2003 Shaposhnikova and Vladimir Maz'ya were awarded the Verdaguer Prize by the French Academy of Sciences[7] for their work resulting in the first scientific biography of Jacques Hadamard.
[12] She found conditions for the boundedness of singular integrals and pseudodifferential operators acting between pairs of Sobolev spaces in 1995.
[15] Based on her researches on the theory of multipliers, T. Shaposhnikova gave various applications of this theory to the study of solutions to second order linear and quasilinear elliptic partial differential equations and systems of such equations: this was a consequence of the fact that, in several cases, such solutions can be considered as multipliers in certain spaces of differentiable functions on a given domain (1986, 1987).
[21] Her recent activity in this field includes the paper (Shaposhnikova 2005) telling three stories of scientists who were forced to answer a mathematical question under rather trying circumstances.
In the 1970s she translated into Russian "The Voyage of the Dawn Treader",[25] "The Silver Chair"[26] and the "Screwtape Letters"[27] by C. S. Lewis.
