Surface Albedo and Spectral Variability of Ceres

Kavli Affiliate: Maria T. Zuber | Summary:Previous observations suggested that Ceres has active but possibly sporadic water outgassing, and possibly varying spectral characteristics in a time scale of months. We used all available data of Ceres collected in the past three decades from the ground and the Hubble Space Telescope, and the newly acquired images […]

Towards a mathematical definition of Coulomb branches of $3$-dimensional $mathcal N=4$ gauge theories, II

Kavli Affiliate: Hiraku Nakajima | Summary:Consider the $3$-dimensional $mathcal N=4$ supersymmetric gauge theory associated with a compact Lie group $G_c$ and its quaternionic representation $mathbf M$. Physicists study its Coulomb branch, which is a noncompact hyper-Kähler manifold with an $mathrmSU(2)$-action, possibly with singularities. We give a mathematical definition of the Coulomb branch as an affine […]
