nLab differential form with logarithmic singularities



A differential form with logarithmic singularities is a meromorphic differential form on some space XX which is a holomorphic differential form on a suitably dense open subspace with at most logarithmic singularities at the boundary.

These are the differential forms on spaces in logarithmic geometry. They form the logarithmic generalization of the holomorphic de Rham complex.
