14 июл. 2014 г. · A function f:X→Y is called invertible if there exists a function g:Y→X such that: y=f(x)⇔x=g(y) for all x∈X and for all y∈Y.

26 июл. 2018 г. · I believe the definition should at the very least state that F must be injective, as this would ensure that F−1 actually is a function. But I ...
