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 SU(2) and Weyl equivariant smooth map where is the configuration space of regular triples in and m, n depend on the initial data We conjecture that, for any the rank of is at least the rank of a collinear configuration in X (collinear when viewed as an ordered r-tuple of points in with r 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.
Acknowledgements
I dedicate this work to Sir Michael Atiyah who came up with the original problem, as well as the question which motivated this work. The author thanks Ben Webster and James Humphreys for their comments on the Mathematics StackExchange website and by email. Any possible mistake in this work is however only the author’s responsibility. I would like to also thank the anonymous reviewer, whose comments made me add more details here and there, resulting in a clearer manuscript.
