The $(3,3)$ torus link produces three unknots that are pairwise linked, which makes me suspect that the borromean rings ─ which are otherwise rather similar ─ cannot be produced through any $(p,q)$ torus link combination, and therefore that there is no deformation of the borromean rings that will make them lie on a torus. However, my knot theory isn't strong enough to make a harder case for this, and there's no mention of any connections in either wikipedia page.
So: can the borromean links be deformed so that they will lay on the surface of a torus? If so, how? If not, why not?
No, the Borromean rings are not a torus link, which is what we call links that can lie on a torus. To quote the wikipedia article on the Borromean rings:
Then we use the fact that every knot or link falls into one of three categories, this time using the wikipedia article on Hyperbolic links:
So, since the Borromean rings are hyperbolic, they cannot be a torus link. Hope this helps.
