Reference excerpt

Vlastimil Dlab (born 5 August 1932) is a Czech-born Canadian mathematician who has worked in Czechoslovakia, Sudan, Australia and especially Canada where he founded and led an influential department of modern mathematics.

Biography Dlab was born on August 5, 1932, in Bzí, Czechoslovakia, a historical village whose territory currently belongs to Železný Brod. He studied at Charles University in Prague, and worked at the Czechoslovak Academy of Sciences for a while in 1956. At Charles University, he was gradually promoted to associate professor. However. Between 1954 and 1964, he was doing university research in Khartoum in Sudan. Between 1964 and 1965 he returned Prague but the Institute of Advanced Studies in Canberra, Australia attracted him between 1965 and 1968. After the 1968 Warsaw Pact invasion of Czechoslovakia, he wasn't quite embraced with open arms. So in 1971, he left for Ottawa, Canada where he founded and led a department of modern mathematics at Carleton University that has significantly influenced the world of algebra, probability, and statistics. Because his father was ill in the early 1980s, Dlab – as an alien – was allowed to visit Czechoslovakia and he restored his relationship with Charles University. In the late 1980s, he taught some courses again there, and he regained full professorship in 1992.

Academic ancestry and collaborators Dlab was a postdoctoral student of renowned Czech mathematician Eduard Čech. While in Canada, Dlab worked as the editor-of-chief of mathematical journals and chairman of assorted organizations and institutions. In 1977, he was elected a fellow of the Royal Society of Canada. Claus Michael Ringel was the co-author of some of the most famous academic works by Dlab, such as the 1976 book Indecomposable representations of graphs and algebras. Dlab helped to educate numerous students of mathematics who became successful by themselves.

Teaching of mathematics In recent years, Dlab was very active in efforts to improve the mathematics education. In the Czech Republic, he's been often quoted as an authority that is skeptical towards modern methods to teach, e.g. the method of Milan Hejný. He emphasizes the key role played by the quality of teachers.

Worked examples

Example 1 — a first encounter with Vlastimil Dlab

Start with the simplest possible case. Write down what Vlastimil Dlab 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 Vlastimil Dlab 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 Vlastimil Dlab 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 Vlastimil Dlab

In research: Vlastimil Dlab 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 Vlastimil Dlab 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: Vlastimil Dlab is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1932 births, 20th-century Czech mathematicians, Academic staff of Charles University, so understanding it makes those chapters shorter.
In everyday life: Look for Vlastimil Dlab 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.
