This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Marilda Sotomayor rather than just read about it. In short: Marilda A. Oliveira Sotomayor (born March 13, 1944) is a Brazilian mathematician and economist known for her research on auction theory and stable matchings.

Key takeaways

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

Reference excerpt

Marilda A. Oliveira Sotomayor (born March 13, 1944) is a Brazilian mathematician and economist known for her research on auction theory and stable matchings. She is a member of the Brazilian Academy of Sciences, Brazilian Society of Econometrics, and Brazilian Society of Mathematics. She was elected fellow of the Econometric Society in 2003 and international honorary member of the American Academy of Arts and Sciences in 2020. She was elected fellow of the International Core Academy of Sciences and Humanities in 2023.

Education Sotomayor grew up in Rio de Janeiro, Brazil. She began her education at Federal University of Rio de Janeiro where she received her degree in Mathematics in 1967. Sotomayor continued her education at Institute of Pure and Applied Mathematics where she received her master's degree in Mathematics in 1972. She received her Ph.D. in Mathematics from Catholic University of Rio de Janeiro in 1981.

Areas of interest Marilda Sotomayor specializes in game theory, matching markets, and market design. She is the only expert in both game theory and matching markets in Brazil.

Personal Sotomayor married Jorge Sotomayor and had two children, a son and a daughter.

Worked examples

Example 1 — a first encounter with Marilda Sotomayor

Start with the simplest possible case. Write down what Marilda Sotomayor 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 Marilda Sotomayor 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 Marilda Sotomayor 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 Marilda Sotomayor

In research: Marilda Sotomayor 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 Marilda Sotomayor 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: Marilda Sotomayor is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1944 births, 20th-century Brazilian economists, 21st-century Brazilian economists, so understanding it makes those chapters shorter.
In everyday life: Look for Marilda Sotomayor 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.
