Jeff Kahn (mathematician)

Jeff Kahn (mathematician) is a mathematics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Jeff Kahn (mathematician) rather than just read about it. In short: Jeffry Ned Kahn is a professor of mathematics at Rutgers University notable for his work in combinatorics. Education Kahn received his Ph.D. from Ohio State University in 1979 after completing his dissertation under his advisor Dijen K.

Key takeaways

Jeff Kahn (mathematician) belongs to mathematics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Jeff Kahn (mathematician) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Jeff Kahn (mathematician) from memory before moving on to harder problems.

Reference excerpt

Jeffry Ned Kahn is a professor of mathematics at Rutgers University notable for his work in combinatorics.

Education Kahn received his Ph.D. from Ohio State University in 1979 after completing his dissertation under his advisor Dijen K. Ray-Chaudhuri.

Research In 1980, he showed the importance of the bundle theorem for ovoidal Möbius planes. In 1993, together with Gil Kalai, he disproved Borsuk's conjecture. In 1996, he was awarded the Pólya Prize (SIAM).

Awards and honors He was an invited speaker at the 1994 International Congress of Mathematicians in Zurich. In 2012, he was awarded the Fulkerson Prize (jointly with Anders Johansson and Van H. Vu) for determining the threshold of edge density above which a random graph can be covered by disjoint copies of a given smaller graph. Also in 2012, he became a fellow of the American Mathematical Society.

Worked examples

Example 1 — a first encounter with Jeff Kahn (mathematician)

Start with the simplest possible case. Write down what Jeff Kahn (mathematician) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Jeff Kahn (mathematician) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Jeff Kahn (mathematician) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Jeff Kahn (mathematician)

In research: Jeff Kahn (mathematician) appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Jeff Kahn (mathematician) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Jeff Kahn (mathematician) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th-century American mathematicians, 21st-century American mathematicians, Combinatorialists, so understanding it makes those chapters shorter.
In everyday life: Look for Jeff Kahn (mathematician) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
