A loss for the CAS community, from William Sit: Dear Friends of Jerry Kovacic:
It is with great sadness that I am passing on the news that Jerry Kovacic died of brain cancer at around 2:30 pm on April 1, 2009. He was 67. Jerry is well known for his eponymous algorithm for solving linear second order differential equations, which was implemented in Scratchpad (Axiom). His early work in the late 1960's on the inverse problem for differential Galois theory paved the way for a complete solution of this difficult problem. He has been a visiting scholar at the Department of Mathematics at The City College of The City University New York since his retirement from a software company, and he has made significant contributions to a modernized treatment of differential algebraic geometry. For the last few years, Jerry was an organizer for the Kolchin Seminar in Differential Algebra, and until a month ago, despite his fight with brain cancer, he continued to attend the Kolchin Seminar at the Graduate Center, CUNY, and participated in discussions. We will miss him dearly.
