Definition of local absolute continuity

437 Views Asked by At

I am studying the notion of absolute continuity. I understood the definition of absolute continuity. I found many references where they use the notion of "local absolute continuity", but I did not find yet a definition of this concept.

Thank you in advance for your answers
