In the fullest generality, a logarithmic transformation consists of locating a torus \(T\) embedded in a 4-manifold \(X\) with trivial normal bundle \(\nu T\approx T\times D^2\), removing \(\operatorname{int}\nu T\) from \(X\) and gluing in \(T^2\times D^2\) by some diffeomorphism \(\phi:T^2\times S^1\to\partial\nu T\).
