The annulus theorem
WebAN ALGEBRAIC ANNULUS THEOREM 463 more work one can show without the torsion free assumption that either the conclusion of Theorem 1.1 holds or there is a subgroup of G which “looks like” a triangle group. Brian Bowditch [2] recently developed a theory of JSJ-decompositions for one-ended hyperbolic groups with locally connected boundary, and ... Webplanar that we prove the then weakened annulus conjecture. If the imbeddings are differentiable or piecewise linear, then it is already known that the annulus conjecture holds for n >6 using the h-cobordism theorems of [7] and [6]. THEOREM 1. Let f, g: S-1 X [-1, 1 ]-4Rn be two imbeddings with disjoint images such that f and g are both ...

In mathematics, the annulus theorem (formerly called the annulus conjecture) states roughly that the region between two well-behaved spheres is an annulus. It is closely related to the stable homeomorphism conjecture (now proved) which states that every orientation-preserving homeomorphism of Euclidean space … See more If S and T are topological spheres in Euclidean space, with S contained in T, then it is not true in general that the region between them is an annulus, because of the existence of wild spheres in dimension at least 3. So the … See more • MathOverflow discussion on the Torus trick • Video recording of interview with Robion Kirby • Topological Manifolds Seminar (University of Bonn, 2024) See more The annulus theorem is trivial in dimensions 0 and 1.

Webannulus with the first normalized Steklov eigenvalue of the critical catenoid. Motivated by all these results, in the second part of this paper, we compare all the Steklov eigenvalues of a general metric and the rotationally symmetric metric on the annulus. It turns out that the comparison is true for a large class of metrics (See Theorem 4.1,
