Nira (Richter) Dyn (Hebrew: נירה דין; born 1942) is an Israeli mathematician who studied geometric modeling, subdivision surfaces, approximation theory, and image compression.
She is a professor emeritus of applied mathematics at Tel Aviv University,[1] and has been called a "pioneer and leading researcher in the subdivision community".
[1] Her dissertation, Optimal and Minimum Norm Approximations to Linear Functionals in Hilbert Spaces, and their application to Numerical Integration, was supervised by Philip Rabinowitz.
[3] After postdoctoral research in the Institute of Fundamental Studies at the University of Rochester, she joined the Tel Aviv faculty in 1972, and retired in 2010.
[1] Dyn was an invited speaker at the 2006 International Congress of Mathematicians, in the section on numerical analysis and scientific computing.
