Another great female mathematician, Marina Ratner, passed away on July 7th, 2017. Marina played in a key role in linking up the Russian and western schools of dynamical systems and later became famous for her beautiful theorems on unipotent flows on homogeneous spaces, and their application to questions in number theory, see for example terrytao.wordpress.com/tag/marina-ratner/
The following is taken from the UC Berkeley website:
She is survived by her daughter Anna Ratner, son-in-law Charles Cox, grandchildren Bryan and Maya, and nephews Michael Bialy (a Professor of Mathematics at Tel Aviv University) and Alex Bialy.
