Helge Holden 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 Helge Holden rather than just read about it. In short: Helge Holden (born 28 September 1956) is a Norwegian mathematician working in the field of differential equations and mathematical physics. He was Praeses of the Royal Norwegian Society of Sciences and Letters from 2014 to 2016.

Key takeaways

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

Reference excerpt

Helge Holden (born 28 September 1956) is a Norwegian mathematician working in the field of differential equations and mathematical physics. He was Praeses of the Royal Norwegian Society of Sciences and Letters from 2014 to 2016. He earned the dr.philos. degree at the University of Oslo in 1985. The title of his dissertation with Raphael Høegh-Krohn was Point Interactions and the Short-Range Expansion. A Solvable Model in Quantum Mechanics and Its Approximation. He was appointed professor at the Norwegian Institute of Technology (now: the Norwegian University of Science and Technology ) in 1991. His research interests are Differential equations, mathematical physics (in particular hyperbolic conservation laws and completely integrable systems), Stochastic analysis, and flow in porous media. In 2014 he became Chairman of the board of the Abel Prize fund. He was elected Secretary General of the International Mathematical Union (IMU) for the period 2019–2022.

Awards and honors He is a member of the Royal Norwegian Society of Sciences and Letters, the Norwegian Academy of Science and Letters and of the Norwegian Academy of Technological Sciences. In 2013 he became a fellow of the American Mathematical Society, for "contributions to partial differential equations". He was elected as a fellow of the Society for Industrial and Applied Mathematics in 2017, "for contributions to nonlinear partial differential equations and related fields, to research administration, and to the dissemination of mathematics". In 2022 he was awarded the Gunnerus Medal for his academic achievement. The Gunnerus Medal is awarded by The Royal Norwegian Society of Sciences and Letters.

Worked examples

Example 1 — a first encounter with Helge Holden

Start with the simplest possible case. Write down what Helge Holden 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 Helge Holden 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 Helge Holden 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 Helge Holden

In research: Helge Holden 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 Helge Holden 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: Helge Holden is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1956 births, Academic staff of the Norwegian Institute of Technology, Academic staff of the Norwegian University of Science and Technology, so understanding it makes those chapters shorter.
In everyday life: Look for Helge Holden 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.
