The ‘Holiverse’: holistic eversion of the 2-sphere in R
نویسنده
چکیده
We give a short, simple and conceptual proof, based on spin structures, of sphere eversion: an embedded 2-sphere in R can be turned inside out by regular homotopy. Ingredients of this eversion are seamlessly connected. We also give the mathematical origins of the proof: the Hopf fibration, and the topological structure of real-projective 3-space.

Sphere Eversions and Realization of Mappings
any (continuous) map N → M between stably parallelizable compact n-manifolds, n 6= 1, 2, 3, 7, is realizable in R, i.e. the composition of f with an embedding M ⊂ R is C-approximable by embeddings. It has been long believed that any degree 2 map S → S, obtained by capping off at infinity a time-symmetric (e.g. Shapiro’s) sphere eversion S×I → R, was non-realizable in R. We show that there exist...
متن کاملThe Minimax Sphere Eversion
We consider an eversion of a sphere driven by a gradient flow for elastic bending energy. We start with a halfway model which is an unstable Willmore sphere with 4-fold orientation-reversing rotational symmetry. The regular homotopy is automatically generated by flowing down the gradient of the energy from the halfway model to a round sphere, using the Surface Evolver. This flow is not yet full...
متن کاملRegular Homotopy and Total Curvature
We consider properties of the total absolute geodesic curvature functional on circle immersions into a Riemann surface. In particular, we study its behavior under regular homotopies, its infima in regular homotopy classes, and the homotopy types of spaces of its local minima. We also consider the total curvature functional on the space of 2-sphere immersions into 3-space in a similar spirit. We...
متن کامل“the Optiverse” and Other Sphere Eversions
For decades, the sphere eversion has been a classic subject for mathematical visualization. The 1998 video The Optiverse shows geometrically optimal eversions created by minimizing elastic bending energy. We contrast these minimax eversions with earlier ones, including those by Morin, Phillips, Max, and Thurston. The minimax eversions were automatically generated by flowing downhill in energy u...

In medical etiquette and ethics, benefit and harm assessment includes risk evaluation, rational risk, distinction between medical and non medical utilitarian considerations, individual and community benefit ratio, and issues of the like. This article explores philosophical foundations of this issue. In philosophy, benefit/harm reduces to pleasure/pain and good/bad. Pleasure (spiritual and non-...
