Michel Las Vergnas

Michel Las Vergnas 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 Michel Las Vergnas rather than just read about it. In short: Michel Las Vergnas (11 January 1941 – 19 January 2013) was a French mathematician associated with Pierre-and-Marie-Curie University in Paris, and a research director emeritus at the Centre national de la recherche scientifique. Las Vergnas earned his Ph.D. in 1972 from Pierre-and-Marie-Curie University, under the supervision of Claude Berge.

Key takeaways

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

Reference excerpt

Michel Las Vergnas (11 January 1941 – 19 January 2013) was a French mathematician associated with Pierre-and-Marie-Curie University in Paris, and a research director emeritus at the Centre national de la recherche scientifique. Las Vergnas earned his Ph.D. in 1972 from Pierre-and-Marie-Curie University, under the supervision of Claude Berge. He was one of the founders of the European Journal of Combinatorics, which began publishing in 1980. His initial research was in graph theory, and particularly in the theories of matching and connectivity. Beginning in 1975, he became one of the pioneers of the theory of oriented matroids, and since that time he was interested in connections between combinatorics and geometry. A workshop on combinatorial geometry, held in Marseille in April 2013, was dedicated to his memory.

Worked examples

Example 1 — a first encounter with Michel Las Vergnas

Start with the simplest possible case. Write down what Michel Las Vergnas 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 Michel Las Vergnas 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 Michel Las Vergnas 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 Michel Las Vergnas

In research: Michel Las Vergnas 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 Michel Las Vergnas 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: Michel Las Vergnas is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1941 births, 2013 deaths, 20th-century French mathematicians, so understanding it makes those chapters shorter.
In everyday life: Look for Michel Las Vergnas 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.
