Lusztig's special pieces conjecture
Daniel Juteau, Paul Levy, Eric Sommers +1
Let be a special nilpotent orbit in the Lie algebra of a simple algebraic group . We give two proofs of the result that every special piece ${\mathcal…

Proving the 6d a-theorem with the double affine Grassmannian
Marco Fazzi, Suvendu Giri, Paul Levy
This paper contains two results of independent interest, the first being more mathematical in nature whereas the second more physical. We first show that the hierarchy of Higgs bra…

Minimal special degenerations and duality
Daniel Juteau, Paul Levy, Eric Sommers
This paper includes the classification, in a simple Lie algebra, of the singularities of Slodowy slices between special nilpotent orbits that are adjacent in the partial order on n…
