Jan Kohlhaase

Jan Kohlhaase is a astronomy 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 Jan Kohlhaase rather than just read about it. In short: Jan Kohlhaase (born 1976) is a German mathematician specialising in the representation theory of p-adic Lie groups and arithmetic geometry. Education and career From 1997 to 2002, Kohlhaase studied mathematics and physics at the University of Hamburg and at Purdue University.

Key takeaways

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

Reference excerpt

Jan Kohlhaase (born 1976) is a German mathematician specialising in the representation theory of p-adic Lie groups and arithmetic geometry.

Education and career From 1997 to 2002, Kohlhaase studied mathematics and physics at the University of Hamburg and at Purdue University. In 2005 he obtained his PhD at the University of Münster under the supervision of Peter Schneider. He subsequently worked at IHES, the University of Münster as well as the University of Heidelberg. Kohlhaase habilitated at the University of Münster in 2011, and was appointed professor for arithmetic geometry at the University of Duisburg-Essen in 2014.

Worked examples

Example 1 — a first encounter with Jan Kohlhaase

Start with the simplest possible case. Write down what Jan Kohlhaase claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Jan Kohlhaase 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 Jan Kohlhaase 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 Jan Kohlhaase

In research: Jan Kohlhaase appears in astronomy 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 Jan Kohlhaase 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: Jan Kohlhaase is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1976 births, 20th-century German mathematicians, 21st-century German mathematicians, so understanding it makes those chapters shorter.
In everyday life: Look for Jan Kohlhaase 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.
