K-equivalence
text:
In mathematics, K -equivalence, or contact equivalence, is an equivalence relation between map germs. It was introduced by John Mather in his seminal work in Singularity theory in the 1960s as a technical tool for studying stable maps. Since then it has proved important in its own right. Roughly speaking, two map germs ƒ, g are K -equivalent if ƒ−1(0) and g−1(0) are diffeomorphic.
