What has the author S K Aiyar written?

There seems to be a little confusion. There isn't a widely known author named "S K Aiyar." It's possible there's a typo or a less common name. Could you please check the spelling or provide more context?

To help me identify the author you're looking for, could you please tell me:

* Full name: Is it "S.K. Aiyar" or "S K Aiyar"?

* Genre: What kind of books do they write (fiction, non-fiction, etc.)?

* Subject area: Are they known for a specific topic like history, economics, or science fiction?

* Any other details: Are they from a specific country or have any other identifying characteristics?

With more information, I can try to find the author you're looking for and list their published works.
