A binary operation on irreducible components of Lusztig's nilpotent varieties {I}: definition and properties
arXiv:2103.12027
Abstract
We define a binary operation on the set of irreducible components of Lusztig's nilpotent varieties of a quiver. We study commutativity, cancellativity and associativity of this operation. We focus on rigid irreducible components and discuss inductive ways to construct them.
