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 theory of linear operators investigates the systematic approximation of functions by sequences of linear mappings acting on function spaces. Central to the field are families of positive ...

Much scientific research across a range of disciplines tries to find linear approximations of nonlinear behaviors. But what does that mean? Spend some time browsing around the web site of MIT’s ...
