Lawvere's account of differential forms in synthetic differential geometry [LOPS18]
Quotes
"Tiny objects are central to Lawvere’s account of differential forms in synthetic differential geometry."
"Tininess is simultaneously unusual and abundant."
"We describe an extension of Martin-L¨of Type Theory that makes a fixed type T tiny by introducing a type former √ for the amazing right adjoint to (T → −)."
"The notion of tininess was anticipated by [KR79; Law79]."
Is there a practical application for the concept of tininess outside of theoretical mathematics
the concept of tininess has practical applications outside of theoretical mathematics. For example, in computer science and programming languages, the idea of representing infinitesimally small quantities or non-standard spaces can be useful for certain algorithms or modeling techniques. Additionally, in physics and engineering, concepts related to tiny objects can be applied to simulations, optimizations, or other computational tasks where precise mathematical representations are required. Overall, the concept of tininess has the potential to find practical use in various fields beyond theoretical mathematics.
