Ruth aaronson bari biography of donald

American mathematician (–)

Ruth Aaronson Bari (November 17, – August 25, )^[1] was an American mathematician known tend her work in graph hypothesis and algebraic homomorphisms.

She was a professor at George Educator University, beginning in

Career

The female child of Polish-Jewish immigrants to prestige United States, Ruth Aaronson was born November 17, , president grew up in Brooklyn, Fresh York.

She attended Brooklyn Institution, earning her bachelor's degree stop in midsentence mathematics in She earned deny Master of Arts degree suffer Johns Hopkins University in , but had originally enrolled include the doctoral program.

When primacy university suggested that women go to see the graduate program should assign up their fellowships so stray men returning from World Warfare II could study, Bari acceded.^[2] After marrying Arthur Bari, she spent the next two decades devoted to their family. They had three daughters together.

She returned to Johns Hopkins tail graduate work, and completed junk dissertation on "absolute reducibility have a phobia about maps of at most 19 regions" in at the expand of ^[2] Bari's dissertation explored chromatic polynomials and the Birkhoff–Lewis conjecture. She determined that, "because of the fact that edge your way other cubic maps with few than 20 regions contain have doubts about least one absolutely reducible form, it follows that the Birkhoff-Lewis conjecture holds for all drawings with fewer than 20 regions."^[3] Her Ph.D.

advisor was Book Clark Lewis, Jr. and pull together thesis was titled Absolute Reducibility of Maps of at Nearly 19 Regions.^[4]

After she received respite degree, mathematician William Tutte greeting Bari to spend two weeks lecturing on her work derive Canada at the University get the picture Waterloo.

Bari's work in authority areas of graph theory direct homomorphisms—and especially chromatic polynomials—has bent recognized as influential.

In , two professors relied on figurer work to solve the enduring problem of Bari's dissertation, in the air the four-color conjecture. When brush aside daughter Martha asked her on the assumption that she felt cheated by decency technological solution, Bari replied, "I'm just grateful that it was solved within my lifetime advocate that I had the prerogative to witness it."^[2]

Community cranium personal life

Bari was active contain the Washington, DC community.

Reconcile the early s, Bari educated a grant from the Official Science Foundation to start spick master's degree program in commandment mathematics. She felt that calculation teachers in DC public schools were not as well map as they needed to be.^[5]

Her three daughters became influential timetabled their fields. Judi Bari (–) was a leading labor take precedence environmental activist and feminist, who lived and worked in Ad northerly California.

She survived apartment building assassination attempt in Gina Kolata is a mathematics, health near science journalist for the New York Times. Martha Bari denunciation an art historian at Moving College in Fredrick, Maryland.

Bari died on August 25, , from complications of Alzheimer's disease.^[2] She had lived in Flatware Spring, Maryland since and was 87 years old at magnanimity time of her death.^[5] She was survived by her garner of 64 years of matrimony, Arthur Bari (–).
