| Abstract: |
The vacua of the mass-deformed ABJM theory are fuzzy spheres, corresponding in the pure ABJM theory to "fuzzy funnel" BPS solutions, both describing M2-M5 systems. I show that contrary to naive expectations, these are fuzzy 2-spheres, not 3-spheres. I show that we have a novel description of the fuzzy 2-sphere in terms of bifundamental matrices, completely equivalent to the usual one (in terms of SU(2) representations), and giving in the classical limit Killing spinors on the 2-sphere. |
