Oleg Marichev

Oleg Marichev 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 Oleg Marichev rather than just read about it. In short: Oleg Igorevich Marichev (Russian: Олег Игоревич Маричев; born 7 September 1945 in Velikiye Luki, Russia) is a Russian mathematician. In 1949 he moved to Minsk with his parents.

Key takeaways

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

Reference excerpt

Oleg Igorevich Marichev (Russian: Олег Игоревич Маричев; born 7 September 1945 in Velikiye Luki, Russia) is a Russian mathematician. In 1949 he moved to Minsk with his parents. He graduated from the University of Belarus, where he continued to study for the Ph.D. degree. His scientific supervisor was Fedor Gakhov. He is the co-author of a comprehensive five volume series of Integrals and Series (Gordon and Breach Science Publishers, 1986–1992) together with Yury Brychkov and A. P. Prudnikov. Around 1990 he received the D.Sc. degree (Habilitation) in mathematics from the University of Jena, Germany. In 1992, Marichev started working with Stephen Wolfram on Mathematica. His wife Anna helps him in his job.

Worked examples

Example 1 — a first encounter with Oleg Marichev

Start with the simplest possible case. Write down what Oleg Marichev 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 Oleg Marichev 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 Oleg Marichev 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 Oleg Marichev

In research: Oleg Marichev 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 Oleg Marichev 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: Oleg Marichev is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1945 births, Belarusian State University alumni, Living people, so understanding it makes those chapters shorter.
In everyday life: Look for Oleg Marichev 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.
