%0 Journal Article %T On spectral minimal partitions: the case of the sphere %A B. Helffer %A T. Hoffmann-Ostenhof %A S. Terracini %J Mathematics %D 2009 %I arXiv %X We consider spectral minimal partitions. Continuing work of the the present authors about problems for planar domains, [23], we focus on the sphere and obtain a sharp result for 3-partitions which is related to questions from harmonic analysis, in particular to a conjecture of Bishop. %U http://arxiv.org/abs/0903.3326v1
