Abstract
In this note, given a pair , where is a complex semisimple Lie algebra and is a dominant integral weight of , where is the real span of the coroots inside a fixed Cartan subalgebra, we associate an and Weyl equivariant smooth map , where is the configuration space of regular triples in , and , depend on the initial data . We conjecture that, for any , the rank of is at least the rank of a collinear configuration in (collinear when viewed as an ordered -tuple of points in , with being the rank of ). A stronger conjecture is also made using the singular values of a matrix representing . This work is a generalization of the Atiyah-Sutcliffe problem to a Lie-theoretic setting.
