An infinite family of Gromoll-Meyer spheres

Bifundamental fuzzy 2-Sphere and fuzzy killing spinors
(2010-12-01)
We review our construction of a bifundamental version of the fuzzy 2-sphere and its relation to fuzzy Killing spinors, first obtained in the context of the ABJM membrane model. This is shown to be completely equivalent to ...

Manifolds with minimal radial curvature bounded from below and big volume

Sharp estimates for eigenvalues of integral operators generated by dot product kernels on the sphere
(Academic PressElsevierSan Diego, 2014-01)
We obtain explicit formulas for the eigenvalues of integral operators generated by continuous dot product kernels defined on the sphere via the usual gamma function. Using them, we present both, a procedure to
describe ...
Centers and limit cycles of vector fields defined on invariant spheres
(Springer, 2021-09-25)
The aim of this paper is the study of the center-focus and cyclicity problems inside the class X of 3-dimensional vector fields that admit a first integral that leaves invariant any sphere centered at the origin. We classify ...

An algorithm to find a maximum of a multilinear map over a product of spheres
(Elsevier, 2012-10-26)
We provide an algorithm to compute the 2-norm maximum of a multilinear map over a product of spheres. As a corollary we give a method to compute the first singular value of a linear map and an application to the theory of ...
