I haven't looked into the book (therefore only a comment), but while the topics listed in the title are relevant for quantum theory, they are generally irrelevant or at most tangentially relevant for General Relativity. Therefore I suspect that it is not the best book if your goal is to understand General Relativity. The most important mathematical topic for General Relativity is differential geometry. I expect all books about that topic to also cover tensors, as they play a central role there.

celtschk‭ so, which book would you suggest? (If you don’t have Link Than, just tell me the book name). And, i want to learn tensor calculus at first then i will read another book for GR (Thats what i have in my mind. But, if you have any book which also covers GR than, Thanks)

I personally learned GR, including the involved mathematics, from the book Gravitation by Misner, Thorne and Wheeler. However that's not a math book, therefore if you want mathematical rigour, that book likely isn't for you (e.g. IIRC you won't find any proofs there). Other than that I don't have specific recommendations, however you might look specifically for books that mention differential geometry and/or relativity theory in the title.
