Knotted tori

Many interesting examples of embeddings are embeddings $S^p\times S^q\to\Rr^m$$<wikitex> Many interesting examples of embeddings are embeddings $S^p\times S^q\to\Rr^m$, i.e. ''knotted tori'' \cite{Alexander1924}, \cite{Milgram&Rees1971}, \cite{Kosinski1962}, \cite{Hudson1963}, \cite{Wall1965}, \cite{Tindell1969}, \cite{Boechat&Haefliger1970}, \cite{Boechat1971}, \cite{Milgram&Rees1971}, \cite{Lucas&Saeki2002}, \cite{Skopenkov2002}, \cite{Skopenkov2006a}, \cite{Cencelj&Repov\v s&Skopenkov2007}, \cite{Cencelj&Repovš&Skopenkov2008}. The classification of knotted tori is a natural next step (after the link theory \cite{Haefliger1966a}) and the Haefliger-Hirsch-Hudson classification of embeddings of highly-connected manifolds) towards the classification of embeddings of ''arbitrary'' manifolds. The classification of knotted tori gives some insight or even precise information concerning arbitrary manifolds and reveals new interesting relations to algebraic topology. Since the general Knotting Problem is recognized to be very hard, it is very interesting to solve it for the important particular case of knotted tori.
