<p>What would you call the product of an annulus and $S^1$ (a 'thickened' torus like 3-manifold)?</p> <p>More generally, is there an archive or list online of names assigned to various (non-standard) manifolds by people? Or a set convention by which to name them?</p>

<p>I would call it a thickened torus. I don't know how standard that is, but it is quite normal to speak of thickened manifolds, where one means that manifold times a closed interval.<br> I have long felt that there should be a mathematical dictionary- not an encyclopaedia, by a dictionary- in order to fix and record standard usage.</p>

<p>that corresponds to the complement of a trivial (but essencial) torus knot in a open solid torus. For those -Fico had mention- they are called cable spaces and have nice foliation into circles. Its name is <strong>CS(1,0)</strong>. Can you see what is CS(2,1)?</p> <p>Edit at: utc-6 = 11:50 approx</p> <p>you could also say <strong>the trivial I-bundle over the torus</strong></p>

<p>May I {humbly} suggest "inner tube", as in "Floating down the river in an ... " ? (Strike while the terminological iron is hot.)</p> <p>Gerhard "Ask Me About System Design" Paseman, 2010.02.09</p>
