A friend of mine asked me yesterday about Santilli's isonumbers. I told him that it was quackery. As I based my answer only on the general reputation of the guy and had no knowledge of the subject, I decided to ask this question here.

Question: Did any serious mathematician spend any time looking at isomnumbers? What is the conclusion? References would be useful.
