  text: We present criteria for establishing a triangulation of a manifold. Given
    a manifold M, a simplicial complex A, and a map H from the underlying space of
    A to M, our criteria are presented in local coordinate charts for M, and ensure
    that H is a homeomorphism. These criteria do not require a differentiable structure,
    or even an explicit metric on M. No Delaunay property of A is assumed. The result
    provides a triangulation guarantee for algorithms that construct a simplicial
    complex by working in local coordinate patches. Because the criteria are easily
    verified in such a setting, they are expected to be of general use.

  text: 'Kleinjohann (Archiv der Mathematik 35(1):574–582, 1980; Mathematische Zeitschrift
    176(3), 327–344, 1981) and Bangert (Archiv der Mathematik 38(1):54–57, 1982) extended
    the reach rch(S) from subsets S of Euclidean space to the reach rchM(S) of subsets
    S of Riemannian manifolds M, where M is smooth (we’ll assume at least C3). Bangert
    showed that sets of positive reach in Euclidean space and Riemannian manifolds
    are very similar. In this paper we introduce a slight variant of Kleinjohann’s
    and Bangert’s extension and quantify the similarity between sets of positive reach
    in Euclidean space and Riemannian manifolds in a new way: Given p∈M and q∈S, we
    bound the local feature size (a local version of the reach) of its lifting to
    the tangent space via the inverse exponential map (exp−1p(S)) at q, assuming that
    rchM(S) and the geodesic distance dM(p,q) are bounded. These bounds are motivated
    by the importance of the reach and local feature size to manifold learning, topological
    inference, and triangulating manifolds and the fact that intrinsic approaches
    circumvent the curse of dimensionality.'

  text: "Isomanifolds are the generalization of isosurfaces to arbitrary dimension
    and codimension, i.e., submanifolds of Rd defined as the zero set of some multivariate
    multivalued smooth function f:Rd→Rd−n, where n is the intrinsic dimension of the
    manifold. A natural way to approximate a smooth isomanifold M=f−1(0) is to consider
    its piecewise linear (PL) approximation M^\r\n based on a triangulation T of the
    ambient space Rd. In this paper, we describe a simple algorithm to trace isomanifolds
    from a given starting point. The algorithm works for arbitrary dimensions n and
    d, and any precision D. Our main result is that, when f (or M) has bounded complexity,
    the complexity of the algorithm is polynomial in d and δ=1/D (and unavoidably
    exponential in n). Since it is known that for δ=Ω(d2.5), M^ is O(D2)-close and
    isotopic to M\r\n, our algorithm produces a faithful PL-approximation of isomanifolds
    of bounded complexity in time polynomial in d. Combining this algorithm with dimensionality
    reduction techniques, the dependency on d in the size of M^ can be completely
    removed with high probability. We also show that the algorithm can handle isomanifolds
    with boundary and, more generally, isostratifolds. The algorithm for isomanifolds
    with boundary has been implemented and experimental results are reported, showing
    that it is practical and can handle cases that are far ahead of the state-of-the-art. "

  text: In this paper we introduce a pruning of the medial axis called the (λ,α)-medial
    axis (axλα). We prove that the (λ,α)-medial axis of a set K is stable in a Gromov-Hausdorff
    sense under weak assumptions. More formally we prove that if K and K′ are close
    in the Hausdorff (dH) sense then the (λ,α)-medial axes of K and K′ are close as
    metric spaces, that is the Gromov-Hausdorff distance (dGH) between the two is
    1/4-Hölder in the sense that dGH (axλα(K),axλα(K′)) ≲ dH(K,K′)1/4. The Hausdorff
    distance between the two medial axes is also bounded, by dH (axλα(K),λα(K′)) ≲
    dH(K,K′)1/2. These quantified stability results provide guarantees for practical
    computations of medial axes from approximations. Moreover, they provide key ingredients
    for studying the computability of the medial axis in the context of computable
    analysis.

  text: The medial axis of a set consists of the points in the ambient space without
    a unique closest point on the original set. Since its introduction, the medial
    axis has been used extensively in many applications as a method of computing a
    topologically equivalent skeleton. Unfortunately, one limiting factor in the use
    of the medial axis of a smooth manifold is that it is not necessarily topologically
    stable under small perturbations of the manifold. To counter these instabilities
    various prunings of the medial axis have been proposed. Here, we examine one type
    of pruning, called burning. Because of the good experimental results, it was hoped
    that the burning method of simplifying the medial axis would be stable. In this
    work we show a simple example that dashes such hopes based on Bing’s house with
    two rooms, demonstrating an isotopy of a shape where the medial axis goes from
    collapsible to non-collapsible.
