nLab logarithmic connection

Idea

The concept of logrithmic connection is that of connection on a bundle in the context of logarithmic geometry. Hence a logarithmic connection is a connection (principal connection or connection on a vector bundle etc.) on some space $X$ whose local connection differential 1-form $A$ is allowed to have logarithmic singularities at a prescribed subspace $D \hookrightarrow X$, hence is allowed to be a differential form with logarithmic singularities.
