4D knots theory

[mersecske]

I need a free description with illustrations on 4D knots theory,
especially the 4D generalization of Reidermeister moves and
the movie represantation.

Where can I find a freely available paper?

Where can I find a freely available paper?

Search for abstracts on the internet then photocopy the content from your local university library?

Please, can anyone give me a usable answer? Thanks

Which part is not usable? Are you unable to find references/abstracts on the internet? Or do you not have access to a suitable university library?

I suspect you'll need a website to find movies, and there are surely free ones. Tried Youtube?

Please tell me some title of papers which introduce 4D knot theory and Reidermeister moves are intruduced as well.
