Fuzzy number approximation techniques aim to represent complex uncertain quantities in a form that is tractable for analysis and computation. Broadly speaking, original fuzzy numbers may be nonlinear ...

Approximation methods in function spaces characterise how well complex functions can be represented or recovered using limited information such as function values or linear measurements. Central to ...

Earlier this summer, we posted about a study that revealed that monkeys could listen to a series of beeps and then equate it to a visual representation of the same number. One of the researchers ...

The ancient Greeks wondered when “irrational” numbers can be approximated by fractions. By proving the longstanding Duffin-Schaeffer conjecture, two mathematicians have provided a complete answer. The ...
