What is Hodge or duality trnsformation? I just know it is an operation to transform tensor of rank p into rank (n-p), where n is the dimension? I want to know more about it especially how it works in general relativity,can anyone give me some introductory reading for me? Thank you(adsbygoogle = window.adsbygoogle || []).push({});
