Shoshana Kamin (born December 24, 1930) is a famous mathematician. She was born in the Soviet Union and later became an Israeli citizen. Shoshana Kamin is known for her important work on partial differential equations. These are special math problems that help us understand how things change over time and space. She also worked on problems in mathematical physics.
About Shoshana Kamin
Shoshana Kamin was born on December 24, 1930. Her birth name was Susanna L'vovna Kamenomostskaya. She studied at Moscow University and graduated in 1953.
In 1959, she earned her "candidate of science" degree from the same university. This is like getting a PhD. Her teacher and mentor was a well-known mathematician named Olga Oleinik.
In the early 1970s, Shoshana Kamin and her two sons left the Soviet Union. She then moved to Israel. There, she became a professor at Tel Aviv University. Today, she is a professor emeritus, which means she is a retired professor who still holds an honored title.
Her Math Discoveries
Shoshana Kamin has made big contributions to mathematics. In the late 1950s, she was the first to prove something very important. She showed that a "generalized solution" existed for the Stefan problem. She also proved that this solution was unique.
The Stefan problem is a math puzzle about how materials change their state. For example, it can describe how ice melts into water. Her teacher, Olga Oleinik, later expanded on Shoshana Kamin's proof.
Shoshana Kamin also did important work on the porous medium equation. This equation helps scientists understand how fluids move through materials with tiny holes, like water in soil. She also studied other types of non-linear elliptic equations. These are complex math problems that describe many natural processes.
One of her important papers was about the "asymptotic theory" of the porous medium equation. In this paper, she signed her name as "S. Kamin (Kamenomostskaya)". This showed both her current and former surnames.
